Our Friday math centers included creating geometric figures

from marshmallows and toothpicks.  What a blast!

We started by reading some fascinating architecture books to look at shapes

in bridges, tunnels, and buildings.  Our favorite was Built to Last.

Can you find any prisms in our creations?  How about any pyramids?  

We can also identify all of the faces, edges, and vertices on our 3-D figures.

Go ahead.  Challenge us to a geometry duel!
