# Four Schools Card Sort

Four high schools (A, B, C, and D) have different numbers of students and different ratios of boys to girls.

- Working with a partner, take turns matching cards that represent the same school.
- Explain to your partner how you know the cards match.
- Your partner should either agree with your explanation or challenge it if your explanation is not correct, clear, or complete.

To match the cards, find a strategy that will help you narrow down the choices. For example, you might start by choosing a school in which the ratio of boys to girls is easy for you to see. Then find all the cards that match that school.
