Day 108: Stacking Dolls

Geometry is working on similarity. Today they went over Dan’s Stacking Dolls. This was a lot of fun!



It took a lot more time for students to ask questions and build on those than it took to actually answer the question. I remembered to go back over their list of questions at the end which brought some good closure.

I asked the extension question of Now I want  you to build a doll as tall as the Empire State Building which contains exactly 100 dolls. We talked about how they would approach it and they found some interesting loop holes of having one mega doll and 99 small dolls inside. Kinda off set the thunder of everything after that.

All in all I believe this was well worth the time and students seemed to enjoy it as well!
