Focus Questions
For use in a classroom, pause the video and ask these questions:
[Pause the video at 3:51] Where do you see 12 – 2 in the picture that Emily and Mauricio drew? Do you agree with the students that the area of the new garden is 90 ft2?
[Pause the video at 5:09] Emily has written 12 • 9 – 2 • 9. Can you describe where each part of that expression can be found or seen in the drawing they made?
Supporting Dialogue
[Pause the video at 0:49] The teacher has asked if it’s okay to make the two expressions equal. In other words, is the equation (12 – y) • 9 = 12 • 9 – y • 9 true? Talk with a neighbor and answer this question.
