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.

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.
