Capitalization Writing Sentences Worksheet

Capital letters tell a reader where a sentence begins and which words are special names, and this capitalization writing sentences worksheet gives first graders focused practice using them. Students learn that the first word of every sentence, the word I, and the names of people and days all start with a capital letter.

The worksheet begins with a worked example that shows a sentence before and after it is fixed. Then students read three short sentences written all in lower case and write each one again with the right capital letters, including a friend’s name and the word I. In the second part, they write two days of the week with a capital. Two writing lines under each sentence give young writers plenty of room.

What’s Included

• One printable 1st grade capitalization worksheet
• A worked example that models the skill
• Three sentences to rewrite with correct capital letters
• Two days of the week to capitalize
• A complete answer key on the second page

Why This Worksheet Helps Kids

Rewriting a whole sentence makes students notice every word, not just the first one, so the rules stick. Mixing the three most common capital letter rules on one page helps children tell them apart and use them together. And copying a sentence neatly on a line builds handwriting and spacing skills at the same time.

Ideas for Teachers and Parents

Before starting, write a sentence about your child’s day with no capitals and let them play detective to find the mistakes. After the page, have them write a sentence of their own that uses their name, the word I, and a day of the week. This capitalization writing sentences worksheet also works well as a morning warm-up, a writing center task, or quick homework.
