Foundational Geometry

In numeracy we have been immersed in a  study of geometric shapes, including pyramids, spheres, cones, cubes, rectangular prisms, triangular prisms, and cylinders. We have been discussing the attributes of these shapes, such as number of edges, vertices, and faces. As a class, two of the trickiest shapes for us to distinguish between have been triangular prisms and pyramids. Today we examined different triangular prisms and pyramids and discussed how to classify each (and why).  Then we had the opportunity to create our own pyramids and triangular prisms using Magnatiles, K'nex, paper, or other building materials. At the end of our explorations we met as a group to share our creations.  We were excited to see how many different ways students came up with to create these two types of shapes. Students sharing their work led to other interesting conversations about different types of pyramids- square pyramids, triangular pyramids, and even hexagonal pyramids. This afternoon we created a venn diagram to compare what we learned about triangular prisms and pyramids.
