### Make 10

1.)Lay out 20 cards on the table. If you don't have 20 cards, you can use the picture provided. You can either play with just the numbered cards or add in face cards as well.Aces are 1, Jacks are 11, Queens are 12, and Kings are 13. 2.) Pick any number of cards and use the order of operations to create an expression that equals 10. See the second picture for an example. Arrange the cards in different orders and use parentheses and operation symbols (+, -, /, x) to make an expression that equals 10. 3.) Once you have created an expression that equals 10, remove those cards from the table. Then continue to create another expression from the cards that are left. As you play, think about the following questions. Can you keep making 10 until there are no cards left? How many different ways can you make 10? What was your longest expression? What was your shortest expression? After you've played, feel free to take a picture of your work and post it. You could also post pictures of the cards and show a few ways you were able to make 10.
