 Today, I'm going to teach two students how to play the difference game. So what they're going to do is they're going to first take a card each, and cards they got were seven and four. And so what they're going to do with pennies, he's going to take seven pennies and he's going to place them in a line. He's going to take the number one. That's on her card, which is a fair place. They're right underneath where he placed his. What number did you get? You want to take those pennies?
