In math we've been learning about polyhedrons!
Here are just a few of the topics we've been discussing:
What's the difference between a prism and pyramid?
What is a tetrahedron?
How many faces does a triangular prim have?
How do you contruct a rectangular prism or cube? That's easy! Use straws and twist-ties!
