This easy worksheet helps second graders tell uppercase letters apart from lowercase ones. Kids sort six letters — B, m, R, s, G, f — into Uppercase (Capital) Letters and Lowercase (Small) Letters boxes. Five fill-in-the-blank sentences explain that uppercase letters are also called capital letters, that lowercase letters are usually smaller, and that we use a capital at the start of a person's name.

A four-question true-or-false section checks ideas like a capital B being taller than a lowercase b and clears up the misconception that every word needs a capital, locking in correct case habits for everyday writing.
