3rd Grade Prefixes worksheets

About this worksheet

Prefixes are word parts added to the beginning of a base word. They change meaning in predictable ways, but the base word usually remains visible. Third graders may know that un means not in one word and fail to transfer that meaning to another, or they may spell a prefix as a separate word. This worksheet focuses on common Grade 3 prefixes: re, un, pre, dis, and mis. Students tell a real prefix from a word that only starts with the same letters, join a prefix to a base with the right spelling, choose the meaning of the new word, find the base word, and match a meaning to a prefixed word.

Each level has its own words, from refill and unlock to rearrange and misunderstand. Encourage your child to cover the prefix, read the base, then uncover the prefix and explain what changed.

What your child will learn

• Identify common prefixes at the start of words
• Combine a prefix with a base word
