I’d say something about student work and messiness, but…this is my work from my full class demo. It gets the idea of dilation across. We struggled with dilating shapes from an external point last year, so this year, we focused on other ways to dilate shapes from a point on the shape itself. We had more luck with rulers and graphs. (And then there was a shark paper, where kiddos tried to dilate a giant shark. Wish I had some photos of that)
What do you notice? What do you wonder?
