In the above example War is being played with a deck of Six-Speed cards. The 2 in 24 is larger than the 1 in 18, but the 8 in 18 is greater than the 4 in 24. By playing this game the child learns that the 2 in 24 is the most important digit when determining which is the greatest.
Many educators play Adding war with their students because it teaches addition in a fun way. Instead of flipping one card as in War, players flip two cards and the player with the greater total takes both.
In case of a tie each player flips two additional face down cards and two additional face up cards. The player with the higher total of face-up cards takes all the played cards. The first player to gain all the cards is the winner.
Speed! cards, Adding War with Speed! adds a whole new dimension to the game. It's a great way to get a mental math workout. Instead of adding mostly single digit numbers, the difficulty increases significantly because players frequently add two digit numbers to determine the winner of the round.
The point is that through play the kids begin to think and develop a deeper understand of numbers and what's actually happening.
Math through play is the best way! To see more ways to use Speed! cards please visit my Speed! Page.
