James Tanton’s incredible Möbius strip cutting project

Today we revisited one of my all time favorite math projects for kids (also **revisiting**) : We did this project once before, but I don’t think the kids remembered it: An absolutely mind blowing project from James Tanton The project is relatively simple to set up – you have strips of paper and make 5 … Continue reading James Tanton’s incredible Möbius strip cutting project

Some beautiful geometry in a challenge problem from Alexander Bogomolny

I did the project below with the boys on Sunday before they went off to camp for a week. The idea wasn’t to get into heavy math, but rather just a relaxed walk through some fun shapes. We got one detail wrong in the 4th video which I was sort of kicking myself for, but … Continue reading Some beautiful geometry in a challenge problem from Alexander Bogomolny
