1. Race to 100

Flip a card and add its value to your running total. First person to reach 100 without going over wins! (Remove face cards for younger players; use these values for older kids: Jack-11, Queen-12, King-13, Ace-0.)

Try for a total of 10

Play this math card game alone or as a team. Lay out 20 cards on the table (leave out face cards or change them to equal 0, while aces equal 1). Remove sets of cards that add up to 10, ultimately trying to remove all the cards from the table. It’s harder than you think!

Declare a fraction war

War is one of the original math card games, but this version adds a fraction aspect. Students deal two cards, a numerator and denominator, then determine whose fraction is the largest. The winner keeps all four cards, and play continues until the cards are gone. If fractions are two hard change it up so that you just play with identify the number and what is larger. Or try dealing to cards and add or subtracting to find out who then has the higher number.

Play a game of “I Spy”

Lay out cards on the table, then take turns giving clues. “I spy two cards that add up to 12.” Differentiate for younger kids with options like, “I spy a card that’s less than 4,” or for older ones: “I spy two cards that are factors of 12.”

Flip to make a prime number

Flip two cards. If you can add, subtract, or multiply them to make a prime number (use one or all of these operations), you get to keep them. First to collect 10 sets of cards wins.
