1. Learning ObjectiveName ______________________ Today, we will use prefixes to analyze1 the meaning of words. 1 carefully look at CFU What are we going to do today? What does analyze mean? Analyze means ______________________________. Activate (or provide) Prior Knowledge Circle the letters at the beginning of the words that are the same. 1. redo 2. rewrite CFU Students, you already know that a letter or group of letters added to words gives the words a new meaning. These are called prefixes. Today, we will use prefixes to analyze the meaning of words.

2. Concept Development • A prefix is a letter or group of letters added to the beginning of a base word to change its meaning. • A prefix has a meaning of its own. A base word is a word in its basic form, without a prefix or suffix. Not an example of a prefix: uncle un-is not a prefix because cle is not a word. reach re- is not a prefix because ach is not a word. CFU What is the difference between the word redo and the word reach? Which word has a prefix? How do you know? A real B rerun In your own words, what is a prefix? A prefix is_________________.

3. Skill Development/Guided Practice • A prefix is a letter or group of letters added to the beginning of a base word to change its meaning. • A prefix has a meaning of its own. A base word is a word in its basic form, without a prefix or suffix. Use prefixes to analyze the meaning of words. Step #1: Read the sentence, paying attention to the underlined word. a. Identify3 the prefix in the underlined word. (circle) b. Write the prefix and its meaning. c. Identify the clues that help know the meaning of the underlined word. (underline) Step #2: Select4 the best definition for the underlined word. (circle) 3 find (synonym) 4 choose (synonym) over, extreme hyper- hyper- over, extreme remove between, among de- inter- inter- remove de- between, among CFU (#1a) How did I/you identify the prefix in the underlined word? (#1c) How did I/you identify the clues that help know the meaning of the underlined word?

4. Sample Test Question:1. Read this sentence. In this sentence, the prefix pre- tells us that A they liked the movie. B they went somewhere before the movie. C they viewed part of a movie before it was out D they enjoyed viewing nice clothes Relevance • A prefix is a letter or group of letters added to the beginning of a base word to change its meaning. • A prefix has a meaning of its own. A base word is a word in its basic form, without a prefix or suffix. 1. Using prefixes to analyze the meaning of words will help you figure out the meaning of more complex words. 2. Using prefixes to analyze the meaning of words will help you do well on tests. Anna and her friends enjoyed the previews at the movie theater. CFU Does anyone else have another reason why it is relevant to use prefixes to analyze the meaning of words? (pair-share) Why is it relevant to use prefixes to analyze the meaning of words? You may give me one of my reasons or one of your own. Which reason is more relevant to you? Why?
