This Grade 4 grammar worksheet helps students understand and practice correct capitalization in sentences and paragraphs. Capitalization is one of the most important rules in writing because it signals the start of sentences, highlights proper nouns, and makes writing clear and organized. Through engaging editing and rewriting exercises, learners develop strong habits for using capital letters correctly.
In this worksheet, students practice identifying capitalization mistakes and correcting them in different contexts. The activities include choosing the correct sentence opening, identifying whether capitalization is correct, filling in missing capital letters, rewriting sentences properly, and editing a full paragraph. These exercises allow learners to apply capitalization rules in real writing situations.
Capitalization helps readers understand sentence structure and meaning. For Grade 4 learners, mastering capitalization rules is important because:
1. Every sentence must begin with a capital letter.
2. The pronoun “I” is always capitalized.

4. Correct capitalization improves readability and writing clarity.
