1st grade complete sentences worksheets

Tap to see another sample sheet.

First grade complete sentences worksheets put a real sentence next to two fragments, one missing its who and one missing its what-happened. Your child circles the complete one. The fragments get sneakier than in kindergarten: they start with capitals, end with periods, and still tell only half an idea.

The kind of sentences you'll get

Circle the letter of the complete sentence.

  1. Mom hangs the photo in the hall.
    Hangs the photo up high.
    The photo of our beach trip.

    Answer: Mom hangs the photo in the hall.

  2. Grandma at the door.
    Grandma waves.
    Waves at me.
  3. The green frog.
    The frog hops.
    Hops to the log.

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 1st grade sheet

1st grade sheets draw from 120 sentences, 6 to a page. All 60 of kindergarten's sentences are here too, plus 60 more. Kindergarten sheets print 5 to a page.

Some of the answers:

Ben reads a book.The bus stops here.Diego digs a hole.The leaves fall.The train comes.A boat floats by.Maya solves the math puzzle.Omar spreads jam on his toast.Zoe bounces the basketball.The mail carrier waves to us.

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

How to teach this

Ask for the two parts by name: the naming part and the telling part. When your child picks a fragment, do not correct it right away. Read it aloud with a puzzled face and ask what is missing. Finishing the fragment out loud (Ran down the hill? WHO ran down the hill?) turns the miss into the lesson.

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 1st grade complete sentences

What makes an item hard at first grade?
The fragments look finished: they start with a capital and end with a period. Your child has to test the idea, not the punctuation, and that is exactly the skill this page drills.
How is this different from the sentence fragments page?
This page asks your child to recognize the complete sentence. The sentence fragments page, which starts at second grade, asks what a broken one is missing. Recognize first, diagnose second.
