Skill Building

From Activity 7.2: MLR 5 Co-Craft Questions. Before revealing the questions in this activity, display the image of the squares with a side length of and invite students to write possible mathematical questions about the diagram. Ask students to compare the questions they generated with a partner before sharing questions with the whole class. Listen for and amplify questions about the total area for each square or the area of each of the nine smaller regions of the squares. If no student asks about the area of each smaller region, ask students to adapt a question to align with the learning goals of this lesson. Then reveal and ask students to work on the actual questions of the task. This routine will help develop students’ meta -awareness of language as they generate questions about area in preparation for the proof of the Pythagorean Theorem.

Extension

From lesson 5 “Are You Ready for More?”: Can we do any better than “between 3 and 4” for √ 12 ? Explain a way to figure out if the value is closer to 3.1 or closer to 3.9.
