Taken from www.math.montana.edu/mathed/distance/capstone/kershner/activities/dice_card.h tml Materials Needed: A deck of cards for each player. Two players required Multiplication War 1. Decide upon values for the face cards. These can vary depending on your goals. For example Jack=11, Queen=12, King=0, Ace=1 and leave the jokers out. 2. Students play in pairs. Begin by shuffling the deck and dealing all cards out to the two players. This game is played quite similarly to traditional "war". 3. The players each turn a card over at the same time. The first person to correctly state the product they see wins the two cards. (For example 9 times 2 is 18.) 4. If there is a tie in naming the product "war" begins. Each player places 2 cards face down, then they simultaneously turn 1 card face up. This continues until one of the players is quicker in giving the number sentence and product. The winner gets to keep all cards that were placed on the table. 5. Play ends when either player has all the cards or after an allotted time. The winner is the player with the most cards. Fact Family Challenge Take turns making up fact-family puzzles for each other. For example, write 2*7=14 at the top of one sheet of paper. Then ask him or her to write the other three sentences in this fact family. (7*2=14, 14/7=2, 14/2=7 Collect the different fact families and use them for practice sessions. Desafio de familias de operaciones Por turnos, inventen rompecabezas de familias de operaciones. Por ejemplo, escriba 2*7=14 en la parte superior de una hoja. Luego pidale que escriba los otros tres enunciados que pertenecen a esta familia. &7*2=14, 14/7=2, 14/2=7) Guarde las diferentes familias de operaciones para practicar en otras sesiones.
