This is a ridiculously fun game I created for my second and fifth graders. It's ridiculous because math is not typically fun, and fun games are not supposed to be free. It works well with players of all ages and levels. Rules are easily modified so people of different abilities can play together.

Materials: 1 - 3 decks of cards. Messed up, incomplete or jumbled together decks may be used.


1. Stack cards in the middle of the table so be easily accessible by all players. For two players, make a draw stack row of five across. For 3 or more, put cards in a 3 x 3 array in the middle of the table. Each player takes five cards face side down in front of them. When all are ready, someone says "Go!"

2. Everyone races to grab cards from the middle stacks simultaneously.

3. You must only have 5 "working cards" to work with in front of you at a time.

4. You can combine your cards to add up to the sum of any multiple of 10: 10, 20, 30. . . Aces are 1, Face cards are 10, Jokers are worth 20. The cards you add up to ten are placed in your positive stack. e.g. - you can move a ten, jack, queen, or king directly to your positive stack since it equals 10. If you "see" an 8, an 8, a 9, and a 5 you can combine those as 30 and place them in your positive stack. The total value of these will be your score. The person with the highest value of tens wins.

5. If you cannot "see" any numbers adding up to ten with the five cards you are working with, you will need to discard a card into your negative stack. Any card placed in the negative stack will equal a penalty depending on the ability level of the player. An advanced adder should have a higher penalty than a basic adder. I always penalize myself "50" points, but my 3rd grade daughter gets only a "10" point penalty for discarding cards.

6. When no more cards are left in the draw stacks, the first person to "see" another persons card makes a ten with one of their own, or that someone at the table has a ten in their working cards they don't see, they can "Steal!" those cards from them.

7. When stealing is over, and no more cards add up to a multiple of 10, add up the total value of the cards. If a player's card total does not equal a multiple of ten, another penalty is applied. I apply a penalty of "100 points" for myself if I end up with anything but a 0 in the ones place for my total, but my 3rd grade daughter gets a lighter penalty of "20 points" for messing up her multiples.

8. Never forget the purpose of the game is to practice math for the sake of improved mental fluency. It's not about the winning. When we play, everyone "wins" because everyone is practicing. We only lose when we give up because the game is too difficult. Make the game as easy as possible so the less advanced players feel successful and they want to play more often.

Modifications to "differentiate" the game for different player ability:

Penalties should be greater for older players.
Use a score multiplier for younger players or a score divider for more advanced players.

Score multiplier is when your daughter has "100 points," but if you give her a score multiplier of "x 2" she essentially gets 200 points. You have to more than double her points to win.

e.g. - I play the game where my 5th grade daughter gets a score multiplier of 2, by my third grader gets a multiplier of 3. I don't win very often, but the girls feel successful, and feel there is a chance they can win. That's the most important thing is that they don't feel discouraged because the challenge level is too great.

Have Fun!
