This worksheet teaches kids that a prefix is a small group of letters added to the beginning of a word to change its meaning. For example, if we add the prefix "un-" to the word "happy," it becomes "unhappy," which means not happy. So, the prefix "un-" changes the meaning of "happy" from feeling good to not feeling good. Adding a prefix is like giving a word a new superpower to make it mean something different!

This worksheet focuses on expanding vocabulary and understanding word structure. Students choose from three common prefixes-dis, re, or un-and attach them to a list of given words. The correct combinations are then written in the space provided, reinforcing phonics patterns and word formation strategies.
