Which mark do 1st graders mix up most?

The exclamation point gets overused because excitement is fun. The fix is a gentle bar: save it for sentences you would actually shout. If you wouldn't shout it, a period is doing the job.

My child writes sentences with no end mark at all. Normal?

Very normal; the thought simply outruns the pencil. A proofreading ritual helps: after writing, touch the end of each sentence and ask, where's the stop sign? The habit transfers from worksheets to their own writing within weeks.

1st grade end punctuation worksheets

First graders read short sentences and supply the end mark themselves. The ear leads: telling sentences fall at the end, questions rise, and excited sentences almost shout their mark.

The kind of sentences you'll fix

Add the end mark to each sentence: a period, a question mark, or an exclamation point.

We read a book
Fixed: We read a book.
When is Mom coming home
Dad naps on the mat

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.

A few of the sentences:

What a pretty song!
We dig in the sand.
Do you want to play?

Fix it. Add the end mark to each sentence: a period, a question mark, or an exclamation point. 6 sentences to fix per page.
Choose the word. Circle the letter of the end mark that finishes each sentence. 10 questions per page.

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

How to teach this

Have your child read the sentence aloud before choosing; the voice almost always knows. When they pick wrong, don't explain, just read the sentence both ways aloud (as a question, as a statement) and let them hear which one the words wanted.

Watch for: Exclamation points mark strong feeling, not just any exciting topic. Most sentences about exciting things still end with a period. A sentence that starts with words like what or where usually asks a question, but not always: 'What a great day!' is an exclamation.
