2nd grade complete sentences worksheets

Second grade complete sentences worksheets use longer word groups, so a fragment can carry plenty of words and still miss its naming part or its action part. Your child picks the complete sentence, which is the same test they will soon run on their own writing.

The kind of sentences you'll get

Circle the letter of the complete sentence.

  1. Covers the log like a rug.
    The soft moss near the creek.
    Moss covers the fallen log.

    Answer: Moss covers the fallen log.

  2. Blows the whistle at noon.

    Our coach blows the whistle.
  3. The popcorn in the big bowl.
    The popcorn spills off the bowl.
    Spills all over the couch.

Every print pulls a fresh set of sentences at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

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

How to teach this

The traps at this level are long fragments that feel complete. When one fools your child, have them underline the who or what, then the action. One of the two underlines will come up empty. That two-part check works on every item here and on every sentence they will ever write.

Watch for: Kids judge by length: a long group of words like 'the big brown dog with the red collar' feels finished but never tells what happened. Short can be complete (Birds fly.) and long can be broken. Kids trust the capital letter and period. A fragment wearing both is still a fragment; have them ask 'who or what?' and 'what happened?' instead of checking the ends.

Common questions about complete sentences

What should my child say when they pick an answer?
Two things: who or what the sentence is about, and what happens. If they can point to both parts, the choice is right. Answers on the key show the complete sentence for every item.
What comes after this skill?
Sentence fragments, where your child names the missing part, and later run-on sentences, where two whole ideas are stuck together. All three build the same habit: checking that every sentence tells one whole idea.
