  • 4. MATH GAME Play this game with a family member. Each player should keep a separate score card. Here’s how to play. Take turns tossing a penny onto the fish pond. If the penny lands on a fish, find its equivalent measure on another fish. Record your “catches” on your scorecard. Then put an X on each of those two fish. You’ve caught them! Keep playing until all the fish in the pond have been caught. If the coin misses a fish or lands on a fish with an X, the fish has gotten away and the next player takes a turn. The player with the greater number of fish wins. 7c 3 1 pt 2 1 yd 4 gal 7 ft 2T 74 in. 15,840 ft 1 4 in. 8 84 in. 4 mi 9,000 lb 6 ft 2 in. 32 pt 1 1 in. 2 4,000 lb 3 ft © Harcourt 3 mi 7,040 yd 41 T 2 FA96 Family Involvement Activities
