When you allow students (these are PreCalculus Honors students) to choose how and where to do their work, you get many different results. Some students worked primarily by themselves and checked in with others at times, some worked in tight pairs, some worked in loose groups of three checking in with each other’s work after every step and asking questions, and some worked completely by themselves. They worked on paper, on horizontal whiteboards, and on vertical whiteboards. On a sunny spring day. Love it. I had to step back and get a panorama.
