Once we had the shoes cut out, students placed their shoe on the appropriate spot on the graph in the hallway.
Today we went out into the hallway and discussed our data. First, I had the students write down something that they noticed about the graph. They noticed some great things! One thing that I did not notice at first, but one of the kids pointed out was that we had two numbers 21 cm long, and 22 cm long that at first glance looked like they had different results (we later put up sticky notes), they actually had the same number in each column. This led to a great discussion!
