We’re starting our geometry unit with the 7th graders with scale. I never mentioned the word “scale” today, but instead gave students a very open ended task: draw an accurate diagram of the classroom. One of my classes spent some time at their desks, looking around and noting things to include in their diagrams. But in another class, every group immediately jumped up, grabbed yard sticks, and started measuring the walls, doors, everything. It was great to see that with no prompting they’re already starting to move toward the idea of scaling down the measurements of the room!
