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. 3rd grade Number Challenge Materials paper and pencil, number cards Step 1 Make a set of number cards by writing a number, 0 through 9, on each card. Place the cards face down on the table. Player 1 turns over three cards. Step 2 Player 1 arranges the 3 digits to make the least possible 3-digit number and records the number. Step 3 Player 2 then rearranges the cards to make the greatest possible number and records it. For example, if the three digits are 5,7,2 the least possible number would be 257 and the greatest possible number would be 752. Ask your child to read both recorded numbers to you. Step 4 Repeat the game several times using 3-digit numbers. Then play using 4 cards, 5 cards, 6 cards, to make large numbers. 3rd grade A prueba con los numeros Materiales papel, lapiz y tarjetas de numeros Paso 1 Haga un conjunto de tarjetas de numeros. Escriba un numero del 0 al 9 en cade una de ellas. Coloque las tarjetas boca abajo sobre la mesa. El jugador numero 1 voltea tres tarjetas. Paso 2 El jugador numero 1 ordena las tarjetas para formar el numero de menor valor posible de 3 digitos y escribe este numero Paso 3 El jugador numero 2 ordena las mismas tarjetas para formar el numero de mayor valor posible de 3 digitos y escribe este numero. Por ejemplo, si los tres digitos son 5,7,y 2, el numero de menor valor posible es 257 y el numero de mayor valor posible es 752. Pida a su hijo(a) que lea en voz alta los dos numeros escritos. Paso 4 Repita el juego varias veces usando numeros de 3 digitos. Luego juegue con 4,5, o 6 tarjetas para formar numeros mas grandes.
