This question tests knowledge of common prefixes and suffixes (CCSS.RF.3.3.a: Identify and know the meaning of the most common prefixes and derivational suffixes). Students must recognize prefixes like un-, re-, pre-, dis-, mis- and suffixes like -ed, -ing, -er, -est, -ly, -ful, -less, -ness, and understand how they change base word meanings. A prefix is a word part added to the beginning of a base word that changes its meaning (un + happy = unhappy means 'not happy'). A suffix is a word part added to the end of a base word that changes its meaning or grammatical function (help + ful = helpful means 'full of help'; jump + ed = jumped means 'did jump in the past'). Common prefixes for grade 3: un- (not), re- (again), pre- (before), dis- (not/opposite), mis- (wrong). Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word kindest has the suffix -est. The base word is kind, which means 'nice'. Adding -est makes it mean 'most kind'. Choice A is correct because the suffix -est means 'most', so kind + est = kindest means 'the most nice'. For example, kindest means most kind, so the kindest student is the most nice one. Choice B is incorrect because it confuses -est with -er— -est means 'most' for 3+ things, not 'more' for 2 things. This error occurs when students confuse comparison suffixes. To help students: For -er/-est, link to comparison (2 things = -er, 3+ things = -est). Provide explicit instruction with examples like tall, taller, tallest before independent practice.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word preview has the prefix pre-. The base word is view, which means 'to look at'. Adding pre- makes it mean 'look at before'. Choice D is correct because the prefix pre- means 'before', so view + pre- = preview means 'to look at something before'. For example, preview means view before, so you preview a book by looking at it before reading. Choice C is incorrect because it is the opposite meaning—pre- means 'before' not 'after'. This error occurs when students misremember affix meanings or focus only on base word. To help students: Connect affix meaning to whole word meaning explicitly, and for -ed/-ing, link to time (yesterday = -ed, today = -ing). Practice with multisensory activities like building words with letter tiles and acting out prefix meanings.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word misread has the prefix mis-. The base word is read, which means 'to look at words'. Adding mis- makes it mean 'read wrong'. Choice A is correct because the prefix mis- means 'wrong', so read + mis- = misread means 'to look at words incorrectly'. For example, misread means read wrong, so if you misread directions, you understand them incorrectly. Choice B is incorrect because it confuses mis- with un- or dis—mis- means 'wrong' not 'not'. This error occurs when students confuse similar affixes like mis- and dis-. To help students: Watch for students who don't recognize affixes in words or confuse affix meanings (un- and re-). Use multisensory activities (build words with letter tiles, act out prefix meanings) to reinforce learning.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word helpful has the suffix -ful. The base word is help, which means 'to assist'. Adding -ful makes it mean 'full of help'. Choice B is correct because the suffix -ful means 'full of', so help + ful = helpful means 'full of assistance'. For example, helpful means full of help, so a helpful person assists others. Choice A is incorrect because it is the opposite meaning— -ful means 'full of' not 'without'. This error occurs when students confuse opposite suffixes like -ful and -less. To help students: Teach opposite pairs (-ful/-less: helpful/helpless; un-/base: happy/unhappy). Practice identifying affixes by underlining/circling them in words and discussing meaning changes.

The base word is play, which means 'to have fun'. Adding -ed makes it mean 'played in the past'. Choice D is correct because the suffix -ed means 'happened before', so play + ed = played means 'had fun in the past'. For example, played means happened before, so yesterday we played means we had fun yesterday. Choice A is incorrect because it confuses -ed with -ing— -ed means 'past' not 'happening now'. This error occurs when students confuse tense suffixes or focus only on base word. To help students: For -ed/-ing, link to time (yesterday = -ed, today = -ing). Use graphic organizers with base word in center and affixed words around it.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word disagree has the prefix dis-. The base word is agree, which means 'to have the same opinion'. Adding dis- makes it mean 'not agree'. Choice B is correct because the prefix dis- means 'not' or 'opposite', so agree + dis- = disagree means 'to not have the same opinion'. For example, disagree means not agree, so if you disagree, you have a different opinion. Choice D is incorrect because it confuses dis- with -ly—dis- means 'not' not 'quickly'. This error occurs when students confuse affix meanings or incorrectly identify the affix. To help students: For -er/-est, link to comparison (2 things = -er, 3+ things = -est). Provide explicit instruction with multiple examples before expecting independent application.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word careless has the suffix -less. The base word is care, which means 'attention or caution'. Adding -less makes it mean 'without care'. Choice C is correct because the suffix -less means 'without', so care + less = careless means 'without attention'. For example, careless means without care, so a careless player doesn't pay attention. Choice A is incorrect because it confuses -less with -ful— -less means 'without' not 'full of'. This error occurs when students confuse opposite suffixes or ignore the suffix. To help students: Create affix anchor charts with meanings and examples. Practice word building with base words like care (careless, careful, caring) to show changes.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word happiness has the suffix -ness. The base word is happy, which means 'feeling good'. Adding -ness makes it mean 'state of being happy'. Choice C is correct because the suffix -ness means 'the state of being', so happy + ness = happiness means 'the state of feeling good'. For example, happiness means the state of being happy, so her happiness showed means her state of feeling good was visible. Choice D is incorrect because it confuses -ness with -er— -ness means 'state of' not 'person who'. This error occurs when students misremember suffix meanings or struggle to combine base + suffix. To help students: Connect affix meaning to whole word meaning explicitly with words like happy (happiness, unhappy). Use multisensory activities like acting out meanings to build understanding.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word unhappy has the prefix un-. The base word is happy, which means 'feeling good'. Adding un- makes it mean 'not happy'. Choice C is correct because the prefix un- means 'not', so happy + un- = unhappy means 'not feeling good'. For example, unhappy means not happy, so if you're unhappy you're not feeling good. Choice A is incorrect because it confuses un- with re—un- means 'not' not 'again'. This error occurs when students confuse similar affixes or misremember affix meanings. To help students: Create affix anchor charts showing common prefixes (un-, re-, pre-, dis-, mis-) and suffixes (-ed, -ing, -er, -est, -ly, -ful, -less, -ness) with meanings and examples. Practice with word building: Start with base word (happy), add affixes (unhappy, happiness, happily, happier, happiest), discuss meaning changes.

Common suffixes: -ed (past), -ing (present), -er (person who/more), -est (most), -ly (manner), -ful (full of), -less (without), -ness (state of). In this question, the word playing has the suffix -ing. The base word is play, which means 'to engage in fun activity'. Adding -ing makes it mean 'playing now'. Choice A is correct because it identifies the suffix -ing as meaning 'happening now'. The suffix -ing means 'happening now', so play + -ing = playing means 'engaging in fun activity currently'. For example, playing means doing play now, so if kids are playing, it's happening at this moment. Choice B is incorrect because it confuses -ing with -ed— -ing means 'present' not 'past'. This error occurs when students confuse tense-related suffixes or misremember affix meanings. To help students: Create affix anchor charts showing common prefixes (un-, re-, pre-, dis-, mis-) and suffixes (-ed, -ing, -er, -est, -ly, -ful, -less, -ness) with meanings and examples. Practice with word building: Start with base word (play), add affixes (playing, played, player), discuss meaning changes.
