Group Activity Cards

Use groups of 3.
Materials: 24 index cards, protractor, straightedge
Pairs of Angles

List the angle measures below onto index cards, one per card. Next, give each player 4 blank index cards and 4 index cards with measures written on them. Each player should draw an angle on a blank index card whose measure is the same as the measure given on a card. For example, if you have a card labeled 25, you should draw a 25° angle on one index card. Draw an angle for each of the 4 measures, one per card.

Angle measures to put on cards:
 
15

25

120

 
25

35

132

 
155

45

112

 
175

18

145

After all the angles are drawn, place all the index cards together and shuffle them. Lay the cards face down in 6 rows with 4 cards in each row. Player 1 begins by flipping over any two of the cards.

The object of the game is to match an angle with its angle measure. Players should use a protractor to verify angle measurement. For example, if player 1 turns over one card that says 35 and a second card with an angle measuring 35°, then those two cards match. Player 1 then keeps those two cards. If the cards do not match return them face down to their original location. Then player 2 can turn over two cards, and so on. If a player makes a match, he or she does not continue playing. Play until all cards are gone. The player with the most cards wins.
