π Topic Summary: Understanding Prefixes
Hey second graders! Have you ever noticed how some words have little parts added to the beginning? These little parts are called prefixes! They change the meaning of a word. Today, we're going to learn about three super helpful prefixes: un-, re-, and pre-.
When you see un- at the start of a word, it usually means "not" or "the opposite of." Think of "unhappy" β it means not happy! When you see re-, it means "again." So, "redo" means to do something again. And finally, pre- means "before." Like "preheat" means to heat something before you use it. Learning these prefixes will help you understand so many new words!
