How to Teach Subject-Verb Agreement to Your Child

By the Practice Buds team · November 2, 2026

Short answer

Subject-verb agreement means the verb has to match the subject in number. One doer takes one kind of verb ("The dog barks"), and more than one doer takes another ("The dogs bark"). Teach your child to find the subject first, decide if it is one or more than one, and then pick the verb. Printable subject-verb agreement worksheets give your child short, repeatable practice with exactly that routine.

Why kids find this hard

Your child has spent years hearing and saying sentences that sound right. Agreement mistakes usually sound fine to them, because they hear the same errors at school and in games, or they simply say what feels natural.

The rule itself also looks backward. A plural noun usually ends in -s ("dogs"), but a present-tense verb that goes with one doer is the one that ends in -s ("barks"). So children see an -s and wonder which word is supposed to carry it.

Then sentences get longer. Once a phrase sits between the subject and the verb, as in "The box of crayons is open," the closest noun ("crayons") pulls the verb the wrong way. Compound subjects like "Mom and Dad" add one more twist.

How to teach it

Plan on 10 minutes with a short list of sentences. Use present tense first, since that is where the -s shows up.

  1. Write a sentence on paper, such as "The dog barks." Ask your child to circle the word that tells who or what is doing the action. That word is the subject.
  2. Ask, "Is that one or more than one?" Write a 1 or a 2 above it.
  3. Teach the "one -s" check for present tense. Usually only one word in the pair gets the -s: "The dogs bark" (the noun has it) or "The dog barks" (the verb has it). Two -s endings or none is a signal to look again.
  4. Have your child read the sentence aloud both ways, then choose the version that matches.
  5. Turn the sentence into its partner. Change "The dog barks" into "The dogs bark," and ask what changed and what stayed the same.
  6. Finish with two sentences your child writes, one with a single doer and one with several.

Worked example

Take this sentence: "The box of crayons ___ open." The choices are "is" and "are."

Step one: find the subject. Cover the phrase "of crayons" with a finger. What is left is "The box ___ open." The subject is "box."

Step two: count it. One box, so the number is 1.

Step three: pick the verb for one doer. "Is" goes with one, so the sentence reads "The box of crayons is open."

Now check it. Uncover the phrase and read it again. "The box is open" sounds right, and nothing about the crayons changes that.

The step that does the work is covering the phrase. Words that come after "of," "in," "with" or "near" belong to a detail, not to the subject. Once your child covers them, the real subject is easy to see.

Common mistakes

Matching the verb to the nearest noun. Your child writes "The box of crayons are open." Spot it by asking which word is closest to the verb. Fix it with the cover-the-phrase step above.

Adding -s to both words. Your child writes "The birds flies." Spot it by counting the -s endings. Fix it with the "one -s" check: "birds fly" or "bird flies," but not both.

Treating a compound subject as one doer. Your child writes "Mom and Dad is coming." Spot it by looking for the word "and" between two names. Fix it by asking how many people are coming. Two people means the verb that fits more than one: "Mom and Dad are coming."

Choosing the verb by how it sounds. Your child says "We was at the park" because it sounds fine at home. Spot it by writing the sentence down and underlining the subject. Fix it by pairing each subject with its verb in a short list: "I am, you are, he is, we are."

Practice ladder

First, around 1st and 2nd grade: simple sentences with one clear doer, such as "The cat runs" and "The cats run." Sort sentences into "one" and "more than one" before choosing verbs.

Next, 2nd and 3rd grade: irregular pairs like "is and are" and "was and were," and sentences with a short phrase between the subject and the verb. Pair this with simple and complete subjects so your child gets good at spotting the real subject.

Later, 3rd through 5th grade: compound subjects, group words, and words like "everyone" and "each." Group words are worth a look on their own, so try collective nouns worksheets alongside. Add proofreading, where your child finds and fixes a mismatched verb in a short paragraph. Conjugating verbs worksheets help here too, since they show how a verb changes from one subject to the next.

FAQ

What grade learns subject-verb agreement? Children meet simple singular and plural subjects in 1st and 2nd grade. The harder cases, such as compound subjects and phrases between the subject and the verb, build through 3rd to 5th grade.

Do I need to teach grammar terms like "subject" and "predicate"? Only "subject" and "verb" to start. Those two words are enough for your child to follow the routine.

Why does my child get it right on a worksheet but wrong when writing? Writing asks your child to think about ideas, spelling and handwriting at once, so agreement slips. A quick read-aloud at the end of a writing session catches most of them.

Is "everyone" singular or plural? Singular. "Everyone is ready" is the standard form, even though the word points to many people. Words like "each," "someone" and "nobody" work the same way.
