Math Games with Playing Cards

I spend a lot of time researching  and playing card games with students to strengthen their number sense. We work on making tens, number order to ten, and smoothly adding and subtracting numbers up to 100 through many different games using playing cards.

Making Ten game

The Making Ten game is great for 2 - 4 players.
Things to remember: A = 1, Jack, Queen, and King = 0

In the center of the table place 4 cards face up. Deal out the rest of the deck equally among players. Do not look at the cards. Just stack your cards face down like in the game of War.
The first player reveals his top card and  if he can make a ten using his card and one of the table cards, he pairs them up and moves them to an area near him. He continues his turn until he cannot make any more tens. 
Play moves around to each player in turn. 
Sometimes there are several face up cards in the middle of the table. That is ok. Eventually you will be left with many picture cards because they will not get used up.
Some of my students were not confident enough in their making ten facts and needed the help of a rekenrek. 
When no more tens can be made, then each player counts up the ten pairs he has and the winner is the player with the most ten pairs.
