# Lesson 10 Multiplication and Division

Let’s represent equal groups and write equal groups situations.

## Warm-up Which One Doesn’t Belong: Multiplication and Division

Which one doesn’t belong?

## Activity 1 Card Sort: Find the Match

Your teacher will give you a card that shows an equation or a diagram.

Find a classmate whose card represents the same situation or quantities as your card does. Be prepared to explain why your cards belong together.

Work with your partner to create a poster that includes:

your cards

a different diagram that your division equation could represent

a situation that your division equation could represent

Show your thinking and organize it so it can be followed by others.

## Activity 2 Find the Match Gallery Walk

As you visit the posters with your partner, answer these questions:

Describe a representation you saw that was different from the ones you showed in your poster.

Choose a poster that is not yours. Describe one way that it shows the relationship between multiplication and division.
