About this resource

Description

Learning to capitalize the first word of every sentence is one of the earliest and most important writing rules, and this Capitalization Beginning of a Sentence Worksheet gives first graders clear, focused practice with that skill. A capital letter at the start of a sentence signals to a reader that a new thought is beginning, and young writers who master this habit early produce neater, easier-to-read work in every subject.

This capitalize the first word of a sentence worksheet is split into two simple parts. In Part A, students read five sentences and circle the beginning letter that should be a capital. In Part B, they rewrite three sentences correctly, starting each one with an uppercase letter. To use it, read a sentence together, ask “Which letter comes first?” and have children mark or rewrite that letter as a capital. A friendly puppy illustration keeps the practice cheerful and inviting.

What’s Included

  • 1 print-ready PDF worksheet
  • Answer key
  • 8 sentence activities (circle the capital and rewrite correctly)

This Capitalization Beginning of a Sentence Worksheet helps children in three key ways. First, circling the beginning letter trains students to look at the very start of a sentence before they write. Second, rewriting whole sentences turns a rule they can name into a habit their hand remembers. Third, the included answer key lets kids check their work and lets teachers grade quickly, so practice stays independent and low-prep.

Teachers and parents can reinforce this skill in playful ways. Hunt for capital letters at the start of sentences in a favorite picture book, write silly sentences on a whiteboard with missing capitals for children to fix, or have kids “be the editor” and correct a grown-up’s lowercase note. Pairing this worksheet with daily journal writing helps the habit of capitalizing the beginning of a sentence stick.
