Kindergarten capitalizing sentences and I worksheets

The kind of sentences you'll fix

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

• Fix it. Cross out each small letter that should be a capital, and write the capital above it. 5 sentences to fix per page.
• Choose the sentence. Circle the letter of the sentence with the correct capital letters. 5 questions per page.

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

How to teach this

Point to the first letter of each option and ask, tall or small? At this age the skill is visual, so keep the question concrete. When your child writes, a gentle "check your first letter" habit at the end of each sentence plants the proofreading routine early.

Watch for: Only the first word gets the starting capital; the other words stay small unless they're names. The word I is capital even in the middle of a sentence.

Common questions about capitalizing sentences and I

Which capital rules come first?

The two on this page: sentences start with a capital, and I is always capital. They cover most of what a kindergarten writer needs, and both are visible at a glance, which makes them ideal first proofreading targets.

My child writes in all capitals. Is that a problem?

It's common and temporary; capitals are easier to form. Keep modeling lowercase and gently request it in practice, but don't panic. The skill on this sheet, noticing which letters should be tall, actually helps the transition along.
