Partner Breakout Room Discussion:

You will have about one minute to talk with your partner about what you remember about using scale drawings to solve problems (Page 19 video).

Older partner will share first! (So figure out each other's birthdays).

Open Ended

Tell me one important thing you remember about using scale drawings to solve problems (it can be anything you remember).

Breakout Room - Peer Teaching

Each partner will BRIEFLY (about a minute) explain how to use the scale of a drawing to find a missing real-world length. You can (and should!) use your notes to help you explain.

I will message you when the second partner needs to begin sharing.

Last partner to join the breakout room will share first!
