This year I really challenged my students to get creative with this lesson. When ever they asked me if it was “good enough” I said “eh… it would be good to get something extra in there…” a lot of students added shading which made it more interesting. Here are some of the examples:
ALSO, I opened up with this warm-up question today. It lead to some really good discussions about how we encode colors and how changing the bits-per-pixel effects our color choices. I had a student from each team put up their best guess and then I put all of their guesses into the widget. It was good to compare what was too light, too yellow, too dark and which one was closest. The person who was closest explained their reasoning for how they got their answers. It was a really good discussion - I felt like there were a lot of “a-ha” moments in both classes after that warm-up.
