10 Facts Mental Math Skills Game (memory card game to promote memorization of "10 facts")
Remove the Kings, Queens and Jacks from a deck of cards and use only two suits (E.g. Heart and Clubs). Shuffle the cards. Place the cards face down on a table in an orderly manner (e.g. grid). The first player turns over 2 cards. If they can be added together to equal 10, the player keeps the cards (E.g. 8 and 2, Ace* and 9, 5 and 5...). If not, the first player turns them back over (in the same spots) and the second player tries to find a match. If the player turns over a 10, they get to keep the 10 (return the second card face down). Continue until all cards are matched.
* Ace counts as 1
