Math GamesPyramid:

Remove all face cards from a deck of playing cards and assign the Ace a value of one. Stack cards face up in a pyramid shape starting with a single card at the top, then two beneath it and three beneath that card. Continue until there are six cards at the bottom of the pyramid. Start by discarding pairs of exposed cards that equal 10 when combined. The game can be made more difficult by discarding any variation of cards that equal ten (such as 5+7-2). The game ends when all possible tens have been discarded. In this and other fun math games, students can time themselves or race against others to complete the challenge.
