Pyramids and their prisms

Today we got our quizzes back, and had some good conversation about how to approach he questions, and how to interpret the results.

Look at all this!  All from a discussion about how a square’s diagonal is related to its side length.

We also checked in on our beans.

We are recording lots of measurements for the next week or two.

Finally we talked about pyramids and the prisms they are related to (with the same base, and the same height)

We predicted how many pyramids full of water we could dump into the prism.  Many thought it’d be 2.  It turns out to be 3, each time, even when the base is a triangle, or a circle.  Pretty neat stuff!
