GUIDE STUDENTS


Review the meanings of the roots equ, min, and ple. Then ask a student to read the directions aloud. Remind students that they may use one or more strategies to find the meaning of each word. Students should under- stand how to apply the three-step process by now; however, you may wish to complete the first item together to be sure. Discuss how first looking at context might help a read- er learn the meaning of profusion. Since the word does not contain any of the roots from this unit, students may need to check the dictionary.


PRACTICE


Have students complete page 131 independently. When they have fin- ished, ask volunteers to give their definitions and explain how they arrived at them. Discuss the similari- ties and differences between stu- dents’ definitions and those in the dictionary.


Reteaching It’s in the Cards


Suggest that students who need extra help work with a partner to create a word memory game for the words in the Word List on page 131. Tell them to write the vocabulary words on one set of colored cards and their definitions on a second set of cards with a different color. Encourage them to use a dictionary to check the definitions. Word and definition cards are also avail- able on the Word Wisdom CD-ROM. Next have them place the cards face down and mix them up. Students then take turns picking up a word card and a definition card. The player decides if the word matches the definition. If it does, the player keeps the pair, and play continues. If it doesn’t, the other player takes a turn. The opposing player can challenge the decision of the player choosing the cards. They then check a dictionary. If the challenger is correct, he or she gets the cards. Players try to col- lect the most cards to win the game.
