### New Lesson Materials - 3D geometry, with a splash of statistics

A new batch of math Lesson Materials went live today! This batch features a unique blend of flavors - mostly geometry (volume of three-dimensional figures), but spiced with a dash of statistics (scatter plots and making estimates):

Prisms and Cylinders - Activity A

Pyramids and Cones - Activity B

Solving Using Trend Lines

How do you find the volume of a prism (or its close cousin, a cylinder)? How much "space" does a pyramid take up compared with a prism? (Or, a cone compared with a cylinder?)

Also, what's a scatter plot, and how can you use them to spot trends in data, and then make reasonable estimates or predictions?

These 3 Gizmos (and the newly-published Lesson Materials) are designed to address those topics.

As always, our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

We're now up to 54 high-school- and middle-school-level math Gizmos with updated Lesson Materials, with more to come.

If you'd like to try these Gizmos, or any of the others in our library, you can sign up for a free trial today!
