This week we decided to play a new math game. The concepts we used weren't knew (addition & subtraction) but the game was new. It lacks a good and proper name, but that doesn't take away from the fun of playing it. In fact, Jayden really got into this game and insisted on pulling out his abacus and sat there adding each set of numbers up trying to determine what the best move was. Honestly, I don't think I've seen him concentrate on anything that hard! It was very unusual to have to wait so long for Jayden to make a move. The idea of the game is to add two cards together to equal the value of a third card. You can, of course, play with addition, subtraction, multiplication, and division. To keep it simple for our first time playing we went with addition, but used a bit of subtraction. Here's how you play:
Take a deck of cards and pull out Aces - 10's. We chose to use Uno cards so we had numbers varying from 0-9. I like using uno cards for math games so the boys can visualize the numbers. We need a new set just for math time! Shuffle the cards and lay 4 cards face up on the table, set the rest aside in a draw pile.
Next, look at the cards and determine if any of the numbers can be added together to reach a third number that is present. In this case we had 5+3=8. The player who's turn it is may take all 3 of the cards. Three more cards are then laid face up to replace those that were taken. Play continues around the table in this fashion.
When you hit a group of cards where no play can be made the player who's turn it is flips over an additional card and places it face up on the table. If nothing can be done the next player in line flips over a card and tries to add them up. Play continues until someone can make a move. When we played, we found that at most 2 cards had to be flipped.
In this case the 1, 1, 5, & 9 couldn't be used in the version we were playing. We drew another card and it was a 6. The player who drew the six can now take the 1+5=6 cards in order to keep play moving. We replaced enough cards onto the table so that there were still 4 cards face up in play. Continue until all cards are used up or no play can be made. We count the cards up to see who has the most if we're trying to determine a winner.
