## Reflection: Intervention and Extension Modeling Real World Data (Day 4 of 4) - Section 2: Gallery Walk

Although the middle part of today’s lesson should be pretty hands off for the teacher. You may need to provide some scaffolds to help students make sense of each other’s questions and to persevere in solving them. Some ideas for scaffolding:

• Allow students to partner up with other classmates
• Give students the option of only solving 12 (thus they can pick and choose which questions make sense to them)
• Ask prompting questions: “What was the given in the problem? What do you want to find out? Which variables are each of these represented by? Or what part of the graph would represent this variable? Where could you look to find the answer?”
• Also, encourage struggling students to look at the different representations of the data to solve the problem. Sometimes it may be hard to solve from the equation, would the graph give us any insight into the behavior of the function? Or maybe the numerical data display would?
