Children learning solids

I was invited once again to teach some 6-7 y.o. children about geometric solids.

We’ve been talking about sphere, cylinder, cone, cube and parallelepiped. I taught them the basics and how to draw/represent them.

Unfolding a cone

Besides, we were focusing on a project where they’ll build a paper dinosaur. I told them about designing and unfolding and how to represent a complex surface using simple solids. E.g.: a dinosaur tail can be split into a cone and some truncated cones. The simply loved the idea!

I’ll tell you more on this story soon. Stay tuned :)
