Making 10 Card Trick

This is a fabulous game/trick for a math center. The students just love trying to make a 10 and it's great practice making 10s. The students would much rather play this trick than completing worksheets any day in my classroom. I think it would be great for 1st or 2nd grade.

For this game you use one deck of cards but remove the jokers.
Face cards- King, Queen, Jack, all equal 10
Ace= 1

The object of the game is to make sums of 10.

First have someone secretly remove two cards and place to the side. (addends) The addends must be greater than 10 when added together. For example, a student could have removed a 6 and a 7. Do not remove face cards or 10s. These two cards will be the missing addends in the very end of the trick.

The students start  by placing three cards out on the table. If a 10 can be made you will cover the two cards that equal 10 ( 2/8, 3/7, 4/6, 5/5, A/9) with cards from the stack. Since Kings, Queens, Jacks, and 10s all equal 10 you only cover them with one card. If a 10 can not be made start a new stack.

When all the cards have been laid out in stacks. You will then find the missing addends that make 10. These groups will be added together. There will be two extra stacks that don't equal 10. The missing stacks that don't make a 10 are the missing addends to the cards the student secretly removed from the beginning.

Here is a little video of my nieces playing this game. This was the first time showing them so it's not perfect.
