Haleemah and ET think about how another student, Amir, is seeing a cobblestone pattern. Then they apply Amir’s method to a new Size Number.

Focus Questions
For use in a classroom, pause the video and ask these questions:
[Pause the video at 3:53] Before Haleemah and ET use Amir’s method to find the number of gray stones in a figure of Size 5, ask your students to do so. Encourage them to also highlight and label each part of their equation or work in the diagram.
[Pause the video at 5:11] Ask your students to consider ET’s claim that the method is “pretty good for finding low Size Numbers.” Ask them what they think he means, and why he might think it isn’t good for larger numbers.
Supporting Dialogue
One of the mathematical tasks ET and Haleemah undertake in this video is making sense of another student’s method for counting the number of gray stones in a cobblestone pattern. Pause the video at 1:13 so that students can see Amir’s work. Ask them to take some time to analyze his method and then talk with a partner about what they think Amir’s method is. Encourage them to discuss what they understand and don’t understand about the method, and also what they like or dislike about it.
After watching the video, display Haleemah and ET’s work (which can be seen at 9:05). Ask your students to restate Haleemah and ET’s ideas in their own words.
