Prefixes for Kids: A Simple Guide with Activities & Printable Lists

Here’s a straightforward way to explain prefixes to children, along with examples, fun activities, and a free printable list.

What Are Prefixes?

A prefix is a small group of letters added to the beginning of a word. By adding a prefix, we can create a new word with a slightly different meaning. For example, the prefix re- means “again,” so when we add it to the word do, we get a new word–redo, which means “to do again.” Another example is the prefix un-, which means “not.” When added to the word happy, we get the new word unhappy, meaning “not happy.”

Engaging Activities for Learning Prefixes

  1. Matching Games: Create a matching game where kids match prefixes with words or definitions. For example, pair re- with do to create redo or un- with do to create undo.
  1. Prefix Hunt: When reading books or even signs along the road, look for prefixes and challenge your child to spot as many as possible as they read.
  1. Prefix Flashcards: Use flashcards with a prefix on one side and example words on the other. This helps reinforce both the meaning of the prefix and its application in words.
  1. Word Creation Challenge: Encourage kids to create their own words by adding prefixes to familiar words. How many words can they make with ex- or im-?
