Kate and Christopher see four little trips of 12 miles in 9 minutes in a diagram that shows a journey of 48 miles in 36 minutes.
For use in a classroom, pause the video and ask this question:
1. [Pause video at 0:49] Where is the times 4 represented in the diagram?
When engaging in the tasks in class, invite your students to build on the work of others by asking students to:
1. Work with a neighbor to identify features of Kate and Christopher’s diagram that you think work well. Then identify features that you would change.
2, Contribute ideas to create a class diagram to show why a car traveling 48 miles in 36 minutes travels at the same speed as a car traveling 12 miles in 9 minutes.
