TITLE: I've Got Your Number AUTHOR: Paula Daniel; Payson Elementary, AZ GRADE LEVEL/SUBJECT: 4-6 Intermediate (adaptable for others). This activity is a math review. OVERVIEW: This activity can be used as a review of material covered in any subject. The number of items can be increased or decreased as needed. PURPOSE: To review material covered in a fun way. The students pay close attention because they're never sure when their answer will be called. OBJECTIVE(s): Students will review concepts, facts, or other skills. RESOURCES/MATERIALS: Unlined cards. Series of problems or questions. ACTIVITIES AND PROCEDURES: Prepare a set of cards. To make a set of cards, plan a series of problems, making sure not to duplicate any of the answers. Starting with the first card, write a problem on the lower half of the card. The answer is on the top of the next card along with the next problem. Continue generating problems until you have at least one card for each student. A card or cards are dealt to each player. Choose one student to start the activity by reading the problem on the bottom of this card to the class. All other students listen carefully to see if their card contains the answer. The student who has the answer reads the answer aloud and then reads the rest of his card to the class. Again, all students listen to see if their card has the answer. Play continues until all cards have been answered and the person who started the review would have the answer to the last problem read. Sample questions. 2 (at top of card) I have two.
