Learning Objectives

Students will learn how to use word parts (prefixes, suffixes and roots) to help determine the meaning of words.


(5 minutes)
  • Write the following word on the board: ANTIDISESTABLISHMENTARIANISM
  • Ask students if they recognize any word or word parts. Have them share the word parts that they see, and as they share, underline or circle those word parts.
    • Example: Anti-dis-establish-ment-arian-ism
  • Have students practice saying the word on the board, just for fun. Students love this word!
  • Explain that when you know what each of the word parts means you can use those meanings as clues to figure out the meaning of the whole word.
  • Ask students if they have heard of any other words that use any of these word parts (prefixes or suffixes).
    • Example: Anti → Antiperspirant. Explain that to perspire is to sweat so what might ANTIperspirant be used for?
