This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root PORT means 'carry,' and the suffix -ABLE means 'able to be.' Combining these parts: PORT-ABLE = carry-able = portable (able to be carried). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: PORT (carry), VIS/VID (see), AUD (hear), SCRIB/SCRIPT (write), DICT (say). Common suffixes include: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'portable' can be broken into parts: PORT + -ABLE. The Latin root PORT means 'carry,' and the suffix -ABLE means 'able to be.' Combining these parts: carry + able to be = able to be carried. Choice A is correct because it accurately reflects the meaning of the root PORT (carry) combined with the suffix -ABLE (able to be). Breaking down the word: PORT=carry + ABLE=able to be = portable=able to be carried. Understanding that PORT means 'carry' helps decode not just this word but also related words like transport, export, import, and support. Choice B is incorrect because it confuses the root PORT (carry) with the root VIS (see). The root for seeing is VIS/VID, as in visible or video, not PORT which relates to carrying. When analyzing words, students must identify the correct root meaning—PORT always relates to carrying, not seeing. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - PORT (carry): portable, transport, export, import, support, report, porter, portfolio; VIS/VID (see): visible, invisible, vision, video, television, supervise; AUD (hear): audience, audible, auditorium, audition, audio. (2) TEACH common affixes - Suffixes: -ABLE/-IBLE (able to be)—portable=able to be carried, visible=able to be seen, audible=able to be heard. (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: port-able. Identify each part: root-suffix. Define each part: PORT=carry, ABLE=able to be. Combine meanings: carry-able = able to be carried = portable. (4) Build WORD FAMILIES - Group words sharing same root (all PORT words: portable, transport, export, import, support, report, porter). Show how different affixes change meaning (porter—one who carries, portable—able to be carried). (5) PRACTICE combining parts - Give students root + suffix, have them build words and meanings: PORT (carry) + ABLE (able to be) = portable (able to be carried), VIS (see) + IBLE (able to be) = visible (able to be seen). Common student errors: Confusing similar roots (PORT=carry vs VIS=see vs AUD=hear), Only giving root meaning without suffix (saying portable=carry instead of able to be carried), Wrong root identification (thinking PORT relates to doors/openings like portal instead of carrying).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root AUD means 'hear,' and the suffix -IBLE means 'able to be.' Combining these parts: AUD-IBLE = hear-able = audible (able to be heard). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: AUD (hear), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write), DICT (say). Common suffixes include: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'audible' can be broken into parts: AUD + -IBLE. The Latin root AUD means 'hear,' and the suffix -IBLE means 'able to be.' Combining these parts: hear + able to be = able to be heard. Choice C is correct because it accurately reflects the meaning of the root AUD (hear) combined with the suffix -IBLE (able to be). The root AUD means 'hear,' and the suffix -IBLE means 'able to be,' so audible means 'able to be heard.' Understanding that AUD means 'hear' helps decode not just this word but also related words like audience, auditorium, audition, audio, and inaudible. Choice A is incorrect because it confuses the root AUD (hear) with the root VIS (see) and adds a negative prefix that isn't present. The root for seeing is VIS/VID, as in visible or invisible, not AUD which relates to hearing. Additionally, 'audible' has no negative prefix like IN-, so it cannot mean 'not able to be' anything. When analyzing words, students must identify the correct root meaning—AUD always relates to hearing, not seeing. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television; PORT (carry): portable, transport, export, import. (2) TEACH common affixes - Suffixes: -ABLE/-IBLE (able to be)—audible=able to be heard, visible=able to be seen, portable=able to be carried. Prefixes: IN- (not)—inaudible=not able to be heard, invisible=not able to be seen. (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: aud-ible. Identify each part: root-suffix. Define each part: AUD=hear, IBLE=able to be. Combine meanings: hear-able = able to be heard = audible. (4) Build WORD FAMILIES - Group words sharing same root (all AUD words: audience, audible, auditorium, audition, audio, inaudible). Show how different affixes change meaning (audible—able to be heard, inaudible—not able to be heard). (5) APPLY to new words - When encountering unfamiliar word with known root, use root as clue: If student knows AUD=hear and sees word 'auditory,' can figure out it relates to hearing. Common student errors: Confusing similar roots (AUD=hear vs VIS=see), Adding prefixes that aren't there (thinking audible has IN- prefix when it doesn't), Wrong root identification (thinking AUD relates to speaking instead of hearing).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root VIS means 'see,' the prefix IN- means 'not,' and the suffix -IBLE means 'able to be.' Combining these parts: IN-VIS-IBLE = not-see-able = invisible (not able to be seen). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: AUD (hear), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write), DICT (say), GRAPH (write/draw), BIO (life), GEO (earth), TELE (far), PHOTO (light). Common affixes include: RE- (again), PRE- (before), IN-/UN- (not), -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'transport' can be broken into parts: trans-port. The prefix TRANS- means 'across.' The root PORT comes from Latin and means 'carry.' Combining these parts: across + carry = carry across. Choice A is correct because it accurately reflects the meaning of both word parts combined. The prefix TRANS- means 'across,' and the root PORT means 'carry,' so transport means 'carry across from one place to another.' Understanding that PORT means 'carry' helps decode not just this word but also related words like portable, export, import, support, and report. Choice B is incorrect because it confuses the root PORT (carry) with the root VIS (see). The root PORT relates to carrying and moving things, not seeing—a word meaning 'see across' would use the root VIS or SCOPE, not PORT. When analyzing words, students must identify the correct root to determine the accurate meaning. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television, supervise, revise; PORT (carry): portable, transport, export, import, support, report; SCRIB/SCRIPT (write): describe, prescribe, script, manuscript, subscription; DICT (say/speak): dictate, predict, contradict, dictionary, verdict; GRAPH/GRAM (write/draw): photograph, autograph, biography, paragraph, telegram; BIO (life): biology, biography, biodegradable, antibiotic; GEO (earth): geography, geology, geometry; TELE (far): telephone, television, telescope, telegraph; PHOTO (light): photograph, photosynthesis. (2) TEACH common affixes - Prefixes: RE- (again), PRE- (before), IN-/IM-/IL-/IR- (not), UN- (not), DIS- (not/away), SUB- (under), TRANS- (across), EX- (out); Suffixes: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION/-SION (act/process), -LESS (without), -LY (in a manner). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: in-vis-ible, trans-port-ation, pre-dict-ion. Identify each part: prefix-root-suffix. Define each part: IN=not, VIS=see, IBLE=able to be. Combine meanings: not-see-able = not able to be seen = invisible. (4) Build WORD FAMILIES - Group words sharing same root (all AUD words: audience, audible, auditorium, audition, audio, inaudible). Show how different affixes change meaning (visible, invisible—IN makes it not; revise—RE makes it again). (5) APPLY to new words - When encountering unfamiliar word with known root, use root as clue: If student knows VIS=see and sees word 'supervisor,' can figure out it relates to seeing/watching over. (6) PRACTICE combining parts - Give students prefix + root + suffix, have them build words and meanings: TRANS (across) + PORT (carry) = transport (carry across), IN (not) + AUD (hear) + IBLE (able to be) = inaudible (not able to be heard). Common student errors: Ignoring prefixes (says predict=say, missing PRE=before so predict=say before), Confusing similar roots (VIS=see vs VIT=live, PORT=carry vs PART=divide), Wrong affix meaning (thinking IN always means 'in' when it often means 'not'), Only giving root without affix (says portable=carry instead of able to be carried), Reversing negative prefix (thinking invisible=able to be seen instead of NOT able to be seen). Remember: PREFIX + ROOT + SUFFIX = complete word meaning.

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root VIS means 'see,' the prefix IN- means 'not,' and the suffix -IBLE means 'able to be.' Combining these parts: IN-VIS-IBLE = not-see-able = invisible (not able to be seen). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: AUD (hear), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write), DICT (say), GRAPH (write/draw), BIO (life), GEO (earth), TELE (far), PHOTO (light). Common affixes include: RE- (again), PRE- (before), IN-/UN- (not), -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'audible' can be broken into parts: aud-ible. The root AUD comes from Latin and means 'hear.' The suffix -IBLE means 'able to be.' Combining these parts: hear + able to be = able to be heard. Choice C is correct because it accurately reflects the meaning of the root AUD and the suffix -IBLE combined. The root AUD means 'hear,' and the suffix -IBLE means 'able to be,' so audible means 'able to be heard.' Understanding that AUD means 'hear' helps decode not just this word but also related words like audience, auditorium, audition, audio, and inaudible. Choice D is incorrect because it confuses the root AUD (hear) with the root VIS (see). The root AUD relates to hearing and sound, not seeing—that would be visible (VIS + IBLE). When analyzing words, students must identify the correct root to determine the accurate meaning. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television, supervise, revise; PORT (carry): portable, transport, export, import, support, report; SCRIB/SCRIPT (write): describe, prescribe, script, manuscript, subscription; DICT (say/speak): dictate, predict, contradict, dictionary, verdict; GRAPH/GRAM (write/draw): photograph, autograph, biography, paragraph, telegram; BIO (life): biology, biography, biodegradable, antibiotic; GEO (earth): geography, geology, geometry; TELE (far): telephone, television, telescope, telegraph; PHOTO (light): photograph, photosynthesis. (2) TEACH common affixes - Prefixes: RE- (again), PRE- (before), IN-/IM-/IL-/IR- (not), UN- (not), DIS- (not/away), SUB- (under), TRANS- (across), EX- (out); Suffixes: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION/-SION (act/process), -LESS (without), -LY (in a manner). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: in-vis-ible, trans-port-ation, pre-dict-ion. Identify each part: prefix-root-suffix. Define each part: IN=not, VIS=see, IBLE=able to be. Combine meanings: not-see-able = not able to be seen = invisible. (4) Build WORD FAMILIES - Group words sharing same root (all AUD words: audience, audible, auditorium, audition, audio, inaudible).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root VIS means 'see,' the prefix IN- means 'not,' and the suffix -IBLE means 'able to be.' Combining these parts: IN-VIS-IBLE = not-see-able = invisible (not able to be seen). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: AUD (hear), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write), DICT (say), GRAPH (write/draw), BIO (life), GEO (earth), TELE (far), PHOTO (light). Common affixes include: RE- (again), PRE- (before), IN-/UN- (not), -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'invisible' can be broken into parts: in-vis-ible. The prefix IN- means 'not.' The root VIS comes from Latin and means 'see.' The suffix -IBLE means 'able to be.' Combining these parts: not + see + able to be = not able to be seen. Choice B is correct because it accurately reflects the meaning of all three word parts combined. The prefix IN- means 'not,' the root VIS means 'see,' and the suffix -IBLE means 'able to be,' so invisible means 'not able to be seen.' Understanding that VIS means 'see' helps decode not just this word but also related words like visible, vision, visual, supervise, and revise. Choice A is incorrect because it reverses the prefix meaning—it ignores that IN- means 'not,' making the word negative rather than positive. The prefix IN- changes 'able to be seen' (visible) to 'NOT able to be seen' (invisible). When analyzing words, students must account for ALL parts—prefix, root, AND suffix—to get the complete meaning. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television, supervise, revise; PORT (carry): portable, transport, export, import, support, report; SCRIB/SCRIPT (write): describe, prescribe, script, manuscript, subscription; DICT (say/speak): dictate, predict, contradict, dictionary, verdict; GRAPH/GRAM (write/draw): photograph, autograph, biography, paragraph, telegram; BIO (life): biology, biography, biodegradable, antibiotic; GEO (earth): geography, geology, geometry; TELE (far): telephone, television, telescope, telegraph; PHOTO (light): photograph, photosynthesis. (2) TEACH common affixes - Prefixes: RE- (again), PRE- (before), IN-/IM-/IL-/IR- (not), UN- (not), DIS- (not/away), SUB- (under), TRANS- (across), EX- (out); Suffixes: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION/-SION (act/process), -LESS (without), -LY (in a manner). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: in-vis-ible, trans-port-ation, pre-dict-ion. Identify each part: prefix-root-suffix. Define each part: IN=not, VIS=see, IBLE=able to be. Combine meanings: not-see-able = not able to be seen = invisible. (4) Build WORD FAMILIES - Group words sharing same root (all AUD words: audience, audible, auditorium, audition, audio, inaudible). Show how different affixes change meaning (visible, invisible—IN makes it not; revise—RE makes it again). (5) APPLY to new words - When encountering unfamiliar word with known root, use root as clue: If student knows VIS=see and sees word 'supervisor,' can figure out it relates to seeing/watching over. (6) PRACTICE combining parts - Give students prefix + root + suffix, have them build words and meanings: TRANS (across) + PORT (carry) = transport (carry across), IN (not) + AUD (hear) + IBLE (able to be) = inaudible (not able to be heard). Common student errors: Ignoring prefixes (says predict=say, missing PRE=before so predict=say before), Confusing similar roots (VIS=see vs VIT=live, PORT=carry vs PART=divide), Wrong affix meaning (thinking IN always means 'in' when it often means 'not'), Only giving root without affix (says portable=carry instead of able to be carried), Reversing negative prefix (thinking invisible=able to be seen instead of NOT able to be seen).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root VIS means 'see,' the prefix IN- means 'not,' and the suffix -IBLE means 'able to be.' Combining these parts: IN-VIS-IBLE = not-see-able = invisible (not able to be seen). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: AUD (hear), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write), DICT (say), GRAPH (write/draw), BIO (life), GEO (earth), TELE (far), PHOTO (light). Common affixes include: RE- (again), PRE- (before), IN-/UN- (not), -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION (process). The word 'microscope' can be broken into parts: MICRO + SCOPE. The prefix MICRO comes from Greek and means 'small.' The root SCOPE comes from Greek and means 'see' or 'watch.' Combining these parts: small + see/watch = device to see small things. Choice B is correct because it accurately reflects the meaning of the root SCOPE. The root SCOPE means 'see or watch' in all related words like telescope (far-see), periscope (around-see), and stethoscope (chest-see/examine). Understanding that SCOPE means 'see/watch' helps decode not just this word but also related words in the SCOPE family. Choice C is incorrect because it confuses SCOPE (see/watch) with SCRIB/SCRIPT (write). The root for 'write' is SCRIB or SCRIPT as in describe, prescribe, or manuscript, not SCOPE. When analyzing words, students must account for ALL parts—prefix, root, AND suffix—to get the complete meaning. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television, supervise, revise; PORT (carry): portable, transport, export, import, support, report; SCRIB/SCRIPT (write): describe, prescribe, script, manuscript, subscription; DICT (say/speak): dictate, predict, contradict, dictionary, verdict; GRAPH/GRAM (write/draw): photograph, autograph, biography, paragraph, telegram; BIO (life): biology, biography, biodegradable, antibiotic; GEO (earth): geography, geology, geometry; TELE (far): telephone, television, telescope, telegraph; PHOTO (light): photograph, photosynthesis; SCOPE (see/watch): microscope, telescope, periscope, stethoscope, horoscope. (2) TEACH common affixes - Prefixes: RE- (again), PRE- (before), IN-/IM-/IL-/IR- (not), UN- (not), DIS- (not/away), SUB- (under), TRANS- (across), EX- (out), MICRO- (small), TELE- (far); Suffixes: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION/-SION (act/process), -LESS (without), -LY (in a manner). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: micro-scope. Identify each part: prefix-root. Define each part: MICRO=small, SCOPE=see/watch. Combine meanings: small-see = device to see small things. (4) Build WORD FAMILIES - Group words sharing same root (all SCOPE words: microscope, telescope, periscope, stethoscope, horoscope). Show how different prefixes change meaning (microscope—see small things, telescope—see far things, periscope—see around things). (5) APPLY to new words - When encountering unfamiliar word with known root, use root as clue: If student knows SCOPE=see and sees word 'kaleidoscope,' can figure out it's a device for seeing beautiful patterns (KALEID=beautiful forms). (6) PRACTICE combining parts - Give students prefix + root, have them build words and meanings: MICRO (small) + SCOPE (see) = microscope (see small things), TELE (far) + SCOPE (see) = telescope (see far things). Common student errors: Confusing similar roots (SCOPE=see vs SCRIB=write), Ignoring context clues (the sentence mentions 'see the tiny cells' which reinforces SCOPE=see), Mixing up root meanings (thinking SCOPE=carry or break). Remember: PREFIX + ROOT + SUFFIX = complete word meaning.

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the prefix PRE- means 'before,' the Latin root DICT means 'say,' and the suffix -TION means 'the act or process.' Combining these parts: PRE-DICT-TION = before-say-process = prediction (the act of saying before something happens). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: DICT (say/speak), VIS/VID (see), PORT (carry), SCRIB/SCRIPT (write). Common affixes include: PRE- (before), -TION/-SION (act/process). The word 'prediction' can be broken into parts: PRE- + DICT + -TION. The prefix PRE- means 'before,' the Latin root DICT means 'say' or 'speak,' and the suffix -TION means 'the act or process.' Combining these parts: before + say + the act of = the act of saying before something happens. Choice B is correct because it accurately reflects the meaning of all three word parts combined. The prefix PRE- means 'before,' the root DICT means 'say,' and the suffix -TION means 'the act or process,' so prediction means 'the act of saying before something happens.' Understanding that DICT means 'say' helps decode not just this word but also related words like dictate, dictionary, contradict, and verdict. Choice A is incorrect because it confuses the root DICT (say) with the root VIS (see). The root for seeing is VIS/VID, as in vision or visible, not DICT which relates to saying or speaking. When analyzing words, students must identify the correct root meaning—DICT always relates to saying/speaking, not seeing. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - DICT (say/speak): predict, dictate, dictionary, contradict, verdict, diction, dictator; VIS/VID (see): vision, visible, revise, supervise; SCRIB/SCRIPT (write): describe, prescribe, manuscript, inscription. (2) TEACH common affixes - Prefixes: PRE- (before)—predict (say before), preview (see before), prepare (make ready before); Suffixes: -TION/-SION (act/process)—prediction (act of saying before), vision (process of seeing), description (act of writing about). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: pre-dict-ion. Identify each part: prefix-root-suffix. Define each part: PRE=before, DICT=say, TION=act of. Combine meanings: before-say-act of = act of saying before = prediction. (4) Build WORD FAMILIES - Group words sharing same root (all DICT words: predict, dictate, dictionary, contradict—all relate to saying). Show how different affixes change meaning (dictate—to say/command, predict—to say before, contradict—to say against). (5) PRACTICE combining parts - Give students prefix + root + suffix, have them build words and meanings: PRE (before) + DICT (say) + ION (act) = prediction (act of saying before), CON (against) + DICT (say) = contradict (say against). Common student errors: Confusing similar roots (DICT=say vs VIS=see vs SCRIB=write), Only giving partial meaning (saying prediction=say, missing PRE=before and TION=act of), Wrong prefix meaning (thinking PRE means not instead of before).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the prefix RE- means 'again,' and the Latin root VIS means 'see.' Combining these parts: RE-VIS-E = again-see = revise (to see again, to look at again). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: VIS/VID (see), AUD (hear), PORT (carry), SCRIB/SCRIPT (write), DICT (say). Common prefixes include: RE- (again), PRE- (before), IN-/UN- (not), TRANS- (across). The word 'revise' can be broken into parts: RE- + VIS + -E. The prefix RE- means 'again,' and the Latin root VIS means 'see.' The -E is a verb ending. Combining these parts: again + see = to look at again or see again. Choice C is correct because it accurately reflects the meaning of the prefix RE- (again) combined with the root VIS (see). The root VIS means 'see,' and the prefix RE- means 'again,' so revise means 'to look at again.' Understanding that VIS means 'see' helps decode not just this word but also related words like visible, vision, supervise, and television. Choice A is incorrect because it confuses the root VIS (see) with the root AUD (hear). The root for hearing is AUD, as in audible or audience, not VIS which relates to seeing. When analyzing words, students must identify the correct root meaning—VIS always relates to seeing, not hearing. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - VIS/VID (see): visible, invisible, vision, revise, supervise, television, video, visual; AUD (hear): audience, audible, auditorium, audio; PORT (carry): portable, transport, export. (2) TEACH common prefixes - RE- (again): revise (see again), rewrite (write again), reread (read again), replay (play again), return (turn again), review (view again). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: re-vis-e. Identify each part: prefix-root-ending. Define each part: RE=again, VIS=see, E=verb ending. Combine meanings: again-see = to see again = revise. (4) Build WORD FAMILIES - Group words sharing same prefix (all RE- words: revise, rewrite, reread, replay, return, review—all mean to do something again). Group words sharing same root (all VIS words: visible, vision, revise, supervise—all relate to seeing). (5) APPLY to new words - When encountering unfamiliar word with known parts, use them as clues: If student knows RE=again and WRITE, can figure out rewrite=write again. (6) Connect to CONTEXT - In the sentence, Sofia will revise her essay 'to improve it,' which makes sense because when you look at something again (revise), you can find ways to make it better. Common student errors: Confusing similar roots (VIS=see vs AUD=hear vs DICT=say), Ignoring prefixes (saying revise=see, missing RE=again so revise=see again), Wrong prefix meaning (thinking RE means not instead of again).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the Latin root VIS means 'see,' the prefix IN- means 'not,' and the suffix -IBLE means 'able to be.' Combining these parts: IN-VIS-IBLE = not-see-able = invisible (not able to be seen). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. The word 'invisible' can be broken into parts: IN- + VIS + -IBLE. The prefix IN- means 'not,' the Latin root VIS means 'see,' and the suffix -IBLE means 'able to be.' Combining these parts: not + see + able to be = not able to be seen. Choice B is correct because it accurately reflects the meaning of the combined word parts. The prefix IN- means 'not,' and VIS means 'see,' so invisible means 'not able to be seen.' Understanding that VIS means 'see' helps decode not just this word but also related words like visible, vision, visual, and supervise. Choice A is incorrect because it confuses the root VIS (see) with the root AUD (hear). The root for hearing is AUD, as in audible, not VIS which relates to seeing. When analyzing words, students must identify the correct root meaning—VIS always relates to seeing, not hearing. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - AUD (hear): audience, audible, auditorium, audition, audio, inaudible; VIS/VID (see): visible, invisible, vision, video, television, supervise, revise; PORT (carry): portable, transport, export, import, support, report. (2) TEACH common affixes - Prefixes: IN-/IM-/IL-/IR- (not), UN- (not), RE- (again), PRE- (before); Suffixes: -ABLE/-IBLE (able to be), -ER/-OR (one who), -TION/-SION (act/process). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: in-vis-ible. Identify each part: prefix-root-suffix. Define each part: IN=not, VIS=see, IBLE=able to be. Combine meanings: not-see-able = not able to be seen = invisible. (4) Build WORD FAMILIES - Group words sharing same root (all VIS words: visible, invisible, vision, visual, supervise, revise). (5) APPLY to new words - When encountering unfamiliar word with known root, use root as clue. Common student errors: Confusing similar roots (VIS=see vs AUD=hear), Ignoring prefixes (saying visible and invisible mean the same), Reversing negative prefix (thinking invisible=able to be seen instead of NOT able to be seen).

This question tests CCSS.L.6.4.b: using common, grade-appropriate Greek or Latin affixes and roots as clues to the meaning of a word by analyzing word parts. Many English words are built from Greek and Latin roots (the base part carrying core meaning) combined with affixes—prefixes (added before the root) and suffixes (added after the root) that modify the meaning. For example, the prefix TRANS- means 'across,' and the Latin root PORT means 'carry.' Combining these parts: TRANS-PORT = across-carry = transport (carry across). Understanding common roots and affixes helps students decode unfamiliar words and expand vocabulary. Common 6th grade roots include: PORT (carry), VIS/VID (see), AUD (hear), SCRIB/SCRIPT (write), DICT (say). Common prefixes include: TRANS- (across), RE- (again), PRE- (before), IN-/UN- (not), SUB- (under), EX- (out). The word 'transport' can be broken into parts: TRANS- + PORT. The prefix TRANS- means 'across,' and the Latin root PORT means 'carry.' Combining these parts: across + carry = carry across from one place to another. Choice A is correct because it accurately reflects the meaning of the prefix TRANS- (across) combined with the root PORT (carry). Breaking down the word: TRANS=across + PORT=carry = transport=carry across from one place to another. Understanding that PORT means 'carry' and TRANS- means 'across' helps decode not just this word but also related words like transfer (carry across), transmit (send across), and transcontinental (across continents). Choice B is incorrect because it confuses the root PORT (carry) with the root VIS (see) and the prefix TRANS- (across) with the prefix RE- (again). The word for 'see again to fix mistakes' would be 'revise' (RE- + VIS), not transport. When analyzing words, students must account for ALL parts—prefix, root, AND suffix—to get the complete meaning. To help students use Greek and Latin roots effectively: (1) TEACH common 6th grade roots systematically - PORT (carry): portable, transport, export, import, support, report, porter; VIS/VID (see): visible, revise, supervise, vision; DICT (say): predict, dictate, contradict. (2) TEACH common prefixes - TRANS- (across): transport (carry across), transfer (carry across), transmit (send across), transcontinental (across continents); RE- (again): revise (see again), rewrite (write again), replay (play again); PRE- (before): predict (say before), preview (see before). (3) BREAK DOWN unfamiliar words into parts - Write word with hyphens: trans-port. Identify each part: prefix-root. Define each part: TRANS=across, PORT=carry. Combine meanings: across-carry = carry across = transport. (4) Build WORD FAMILIES - Group words sharing same prefix (all TRANS- words: transport, transfer, transmit, transform, translate). Group words sharing same root (all PORT words: transport, export, import, portable). (5) PRACTICE combining parts - Give students prefix + root, have them build words and meanings: TRANS (across) + PORT (carry) = transport (carry across), EX (out) + PORT (carry) = export (carry out), IM (in) + PORT (carry) = import (carry in). Common student errors: Ignoring prefixes (saying transport=carry, missing TRANS=across so transport=carry across), Confusing similar prefixes (TRANS=across vs RE=again), Wrong root meaning (thinking PORT=door instead of carry).
