This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word disagree has the prefix dis- added to the base word agree. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is agree which means to have the same opinion. The prefix is dis- which means not. To find the whole word's meaning, we combine these: not + agree. Choice B is correct because it properly combines the meanings. Agree means to have the same opinion and dis- means not, so disagree means not agree. This follows the pattern for dis-: not + base. Choice A is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of dis-. Students make this error when they confuse similar affixes like dis- and re-. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.

This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word teacher has the suffix -er added to the base word teach. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is teach which means instruct. The suffix is -er which means person who. To find the whole word's meaning, we combine these: person who + teach. Choice B is correct because it properly combines the meanings. Teach means instruct and -er means person who, so teacher means a person who teaches. This follows the pattern for -er: person who + base. Choice C is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of -er. Students make this error when they confuse prefixes with suffixes or don't know the affix meaning. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.

This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word misplace has the prefix mis- added to the base word place. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is place which means to put something in a spot. The prefix is mis- which means wrong. To find the whole word's meaning, we combine these: wrong + place. Choice A is correct because it properly combines the meanings. Place means to put something in a spot and mis- means wrong, so misplace means place something in the wrong spot. This follows the pattern for mis-: wrong + base. Choice B is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of mis-. Students make this error when they confuse similar affixes like mis- and re-. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning.

This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word quickly has the suffix -ly added to the base word quick. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is quick which means fast. The suffix is -ly which means in that way. To find the whole word's meaning, we combine these: in that way + quick. Choice A is correct because it properly combines the meanings. Quick means fast and -ly means in that way, so quickly means in a fast way. This follows the pattern for -ly: in that way + base. Choice B is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for -less instead of -ly. Students make this error when they confuse similar suffixes like -ly and -less. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning.

Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is sad which means unhappy. The suffix is -ness which means state of being. To find the whole word's meaning, we combine these: state of being + sad. Choice C is correct because it properly combines the meanings. Sad means unhappy and -ness means state of being, so sadness means the state of being sad. This follows the pattern for -ness: state of being + base. Choice A is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for un- instead of -ness. Students make this error when they confuse prefixes with suffixes or don't combine both parts. To help students: Teach common affixes and their meanings.

This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word quickly has the suffix -ly added to the base word quick. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Suffixes go at the end (slow-ly, care-ful). The suffix -ly means 'in that way' or 'in the manner of,' so when we add it to an adjective, it tells how something is done. In this word, the base word is quick which means fast. The suffix is -ly which means in that way. To find the whole word's meaning, we combine these: quick (fast) + ly (in that way) = in a fast way. Choice B is correct because it properly combines the meanings. Quick means fast and -ly means in that way, so quickly means in a fast way or doing something fast. This follows the pattern for -ly: slowly (in a slow way), quietly (in a quiet way), carefully (in a careful way). Choice C is incorrect because it confuses -ly (in that way) with -er (person who). Students make this error when they mix up different suffix meanings. To help students: Teach common suffixes and their meanings. Practice breaking words into parts: base word + suffix. Strategy: (1) Cover the suffix, identify base word and its meaning. (2) Uncover suffix, identify what it means. (3) Combine: base meaning + suffix meaning = new word meaning. Examples: quick (fast) + ly (in that way) = quickly (in a fast way). slow + ly = slowly (in a slow way). Practice with word families (quickly, slowly, quietly - all -ly meaning in that way).

This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word misplace has the prefix mis- added to the base word place. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, mis-spell). The prefix mis- means 'wrong' or 'badly,' so when we add it to a base word, it means doing that action incorrectly. In this word, the base word is place which means put something somewhere. The prefix is mis- which means wrong. To find the whole word's meaning, we combine these: wrong + put something somewhere = put something in the wrong place. Choice A is correct because it properly combines the meanings. Place means put something somewhere and mis- means wrong, so misplace means to put something in the wrong place or lose track of where you put it. This follows the pattern for mis-: misspell (spell wrong), misbehave (behave wrong), misunderstand (understand wrong). Choice B is incorrect because it confuses mis- (wrong) with re- (again). Students make this error when they mix up different prefix meanings. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify base word and its meaning. (2) Uncover prefix, identify what it means. (3) Combine: prefix meaning + base meaning = new word meaning. Examples: mis (wrong) + place (put somewhere) = misplace (put in wrong place). mis (wrong) + spell = misspell (spell wrong). Practice with word families (misplace, misspell, misbehave - all mis- meaning wrong).
