Students take a walk around the school and develop mathematical questions about their school community. The walk can focus on one particular area of the school or the surrounding community. Then students choose a question to answer. They make a plan of how to answer the question with their partner and determine which tools they will need to answer the question. These activities can happen over the course of two days to allow students time to answer multiple questions.

If students need additional support with the concepts in this lesson, refer back to Unit 4, Section B in the curriculum materials.

MP1 asks students to make sense of problems and persevere in solving them. MP5 asks students to use appropriate tools strategically. Where did you see evidence of students engaging in these mathematical practices throughout the lesson?
