What is subject-verb agreement in simple terms?

The action word changes to match how many are doing it. One dog barks; two dogs bark. Kids mostly know this by ear already from speaking. The worksheet turns that ear into a habit they can use while writing.

Why does the verb get an s for one dog?

English is odd here: the s that makes nouns plural makes verbs singular. For regular nouns with regular verbs, a handy check: "the dog barks" and "the dogs bark" each carry one s, while "the dogs barks" carries two. It is a quick alarm bell, not a law; words like children or bus need the one-or-many question instead.

2nd grade subject-verb agreement worksheets

Subject-verb agreement means the verb matches who is doing the action: one dog barks, two dogs bark; she runs, they run. Second graders write the verb that fits a simple subject, building the ear for "one or more than one."

The kind of sentences you'll fix

Write the form of the verb in parentheses that agrees with the subject. Use the present tense unless the sentence says it already happened.

A crab (dig) in the sand.
Fixed: A crab digs in the sand.
Ben (draw) a red bus.
Lucia (read) a book about volcanoes.

Every print pulls a new set of sentences at this level, so a make-up test or a second sibling gets a different mix.

What's on a 2nd grade sheet

A few of the sentences, as the answer key corrects them:

Fix it. Write the form of the verb in parentheses that agrees with the subject. Use the present tense unless the sentence says it already happened. 7 sentences to fix per page.

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Train the ear before the rule: say both versions out loud ("the dog bark / the dog barks") and let your student pick what sounds right, then show why. The one-or-many question is the whole game at this level, so have them circle the subject and say "one" or "more than one" before choosing.

Watch for: The s moves: singular nouns usually have no s while their verb does (the dog barks), and plural nouns have the s while their verb doesn't (the dogs bark). Words between the subject and the verb don't change the match. In 'The box of crayons was full', the subject is box, not crayons.
