Our similarity unit doesn’t really have a project. We had a picture project where we dilated candy bar wrappers when we taught the course 2 years ago, but it was more a project than mathematics (and they aren’t mutually exclusive, though we didn’t strike that balance here), so we shortened it to one day. Fascinating to watch students take art and grapple with how to make it bigger. Not pictured: Sailor Moon or an elephant.What do you notice? What do you wonder?
