Focus Questions
For use in a classroom, pause the video and ask these questions:
[Pause the video at 1:28] Ask students to use the equation that ET and Haleemah developed (or their own, if they prefer) to find the number of gray stones in Size 11. Ask them to draw a picture of the Size 11 figure and connect each part of their equation to features in their picture. After watching Haleemah and ET work, ask them to compare their work to what they saw in the video.
[Pause the video at 3:40] Ask students to examine Haleemah and ET’s drawing and describe how they think ET and Haleemah might see each part of their equation in that diagram.
Supporting Dialogue
After students have had a chance to work on finding the number of gray stones in Size 11, or have finished watching this episode, ask them to consider the work of a fictional student. Say “There was a student who said it was easier to find three times eleven squared, and then add eleven. Does that work? Will it work for any number? How do you know?”
