Discussion Questions

Before the Game

8+2=10, how many other number sentences can you write with a sum of 10?

Which of these numbers would you combine to make this equation easier to add 1+4+9?

Could you break up the 5 in this number sentence to make it easier to subracts 14-5?

Can you find the sum of 8+6 by counting on?

After the Game

In this game, you either tapped the arrow up or down to make a ten; did you see that the number of times you had to tap was how many more or less you had to add to the number to make it a ten?

When you moved the line to take away from one number to make the other a ten at the beginning of the game, did you see that you were adding to one number and taking away from the other?

Why is it easier to add 2 numbers when one of them is a 10?

Why is it easier to subtract 2 numbers when one of them is a 10?
