Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Knowing the surface area certainly helps when deciding how much paint to buy before a project. Scholars solve for surface area, as well as volume and area, as part of the presentation from Grade 6 Claim 1 Item Slide Shows. Geometric...

How do you know you know? Prove it! The guide goes through several examples and includes a link to a video to teach learners how to work through coordinate proofs. The goal is to prove that different shapes are indeed that shape. 

Young mathematicians find the surface area and volume of a square pyramid and a cone. In what looks like a typical activity out of a textbook, you'll find an activity where learners find an unknown measurement of a pyramid or...
