We match nouns and verbs. 'The cats' means more than one. We use 'jump' without 's' for many cats.

This question tests 1st grade subject-verb agreement (CCSS.L.1.1.c: Use singular and plural nouns with matching verbs in basic sentences). In sentences, the naming word (noun) and action word (verb) must match. When the subject is ONE (the cat, Emma, he), the verb gets -s or -es (jumps, runs, hops). When the subject is MORE THAN ONE (the cats, they, the boys), the verb does NOT get -s (jump, run, hop). The choices present sentences, and the task is to identify the one with a mistake. Since 'The boys jumps' has a plural subject with a singular verb, it shows mismatched agreement. Choice C is correct because it identifies the error where 'The boys' is MORE THAN ONE, but the verb has -s: jumps, which should be jump. Choice B represents a correct sentence but is a distractor for students who miss the error type. Students make this error because they overgeneralize the plural -s rule to verbs. To help students: Use visual aids showing 'one/more than one' with verb forms. Create sentence strips: 'The boys ___' (jump/jumps) and have students choose. Practice chant: 'One gets -s' (point to singular), 'More than one, no -s' (point to plural). Use subject-verb cards to match. Watch for: The confusing rule that singular SUBJECTS don't have -s (the boy = no s on boy) but singular VERBS DO have -s (jumps = has s). This is opposite of plural SUBJECTS that DO have -s (the boys) but plural VERBS DON'T (jump). Key memory aid: ONE → add -s to verb (the boy jumps), MORE THAN ONE → no -s on verb (the boys jump).

When the subject is MORE THAN ONE (the cats, they, the boys), the verb does NOT get -s (jump, run, hop). The sentence shows multiple dogs doing the action now. Since the subject is plural, the verb must not have -s to match. Choice B is correct because 'The dogs' is MORE THAN ONE, so the verb does NOT have -s: sleep. Choice A represents singular-plural reversal with the singular verb 'sleeps' for a plural subject. Students make this error because they forget singular verbs need -s and overgeneralize the plural -s rule. To help students: Use visual aids showing 'one/more than one' with verb forms. Create sentence strips: 'The dogs ___' (sleep/sleeps) and have students choose. Practice chant: 'One gets -s' (point to singular), 'More than one, no -s' (point to plural). Use subject-verb cards to match. Watch for: The confusing rule that singular SUBJECTS don't have -s (the dog = no s on dog) but singular VERBS DO have -s (sleeps = has s). This is opposite of plural SUBJECTS that DO have -s (the dogs) but plural VERBS DON'T (sleep). Key memory aid: ONE → add -s to verb (the dog sleeps), MORE THAN ONE → no -s on verb (the dogs sleep).

In sentences, the naming word (noun) and action word (verb) must match. When the subject is ONE (the cat, Emma, he), the verb gets -s or -es (jumps, runs, hops). When the subject is MORE THAN ONE (the cats, they, the boys), the verb does NOT get -s (jump, run, hop). The choices present sentences with 'he' hopping fast. Since the task is to identify a correct sentence, we look for proper matching. Choice B is correct because 'He' is ONE person, so the verb needs -s: hops. Choice A represents singular-plural reversal with the plural verb 'hop' for a singular subject. Students make this error because they're learning the opposite pattern from nouns (add -s for plural) and apply it incorrectly to verbs. To help students: Use visual aids showing 'one/more than one' with verb forms. Create sentence strips: 'He ___' (hops/hop) and have students choose. Practice chant: 'One gets -s' (point to singular), 'More than one, no -s' (point to plural). Use subject-verb cards to match.
