problem_activity: Narrative
The purpose of this warm-up is to elicit the mathematical questions that students produce about shapes composed of pattern blocks, which will be useful when students create and ask questions about shapes in a later activity. While students may notice and wonder many things about the shape, the questions that students can answer about the image are the important discussion points. As students discuss and justify their questions and answers, they share a mathematical claim and the thinking behind it (MP3).

Activity Synthesis
Reread each of the questions that students shared.
As you read each question, ask: “Can we figure out the answer to this question? How?” (We can figure out how many blue rhombuses she used by counting. We would have to ask Mai why she didn’t use any square pattern blocks.)
