I’ve been reading About Teaching Mathematics by Marilyn Burns and it is chock full of great ideas. I came across this game in my reading today and made a few tweaks. It is ideal for home schoolers because kids can play it on their own.
Start with a deck of cards and remove all of the face cards. The aces are ones in this game.
Shuffle the cards. Flip over 7 in a row. If there are any tens or any pairs of cards that make ten remove them and place them face up in the discard pile. I like to keep mine organized by pair so you can easily see all the different ways to make a ten.
Deal new cards to replace those in the row of seven.
Continue dealing and making pairs. If you ever get a whole row of 7 with no possible pairs, start a new row of 7 above. These cards can be paired with each other or with the first row.
If you don’t make any mistakes, no card will be left without a pair. It is a great way to test for errors! And it is kind of fun to watch the deck of cards gradually disappear into pairs of ten.
