Nine children want to play a game. They need to be in teams of two. Find out how many teams of two there will be and whether any student would be left out.

Let’s draw a picture to represent this scenario. Okay, so here are our nine players. And they need to be put in teams of two. There’s team one, team two, team three, and team four. But this player doesn’t have another person to play with him. He is left out. In this case, we have four teams and one left out. That’s how you would solve this problem, by drawing a picture.

But what if there were 87 children? You wouldn’t wanna draw a picture of 87 children. So maybe we need another strategy to solve this problem. Putting the students in groups of two is the same thing as dividing nine by two.

To divide nine by two, I need to think of numbers that are multiplied by two that are close to nine. Two times some number is about nine. We’re close to nine. Two times four is eight. And that’s pretty close to nine. Two times four equals eight plus one equals nine. There will be four teams and one remaining, one left out.
