At-home Practice:
Supplies:
deck of cards (Remove face cards)
This is a great math card game. Players divide the deck of cards evenly amongst themselves. Each player takes two cards and places them, face down, on the game mat (one card in each column).
Each player turns over the two cards to make a two-digit number. Both players call out their numbers while verbalizing it (i.e. Three tens and four ones equals 34). The player with the largest number takes all four cards.
If there is a draw (both players have the same number), war is declared. Each player takes two more cards, place them on the Game Mat, and adds that second number to the first number (the one they tied with). The player with the largest sum takes all 8 cards.
The game ends when one player has all of the cards.
