Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

Shape one's understanding of geometry using the resource. The sixth of seven chapters in 6th Grade Math focuses on geometry principles. Future mathematicians learn to find the area of parallelograms, trapezoids, triangles, and other...

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. 

Explore surface areas and nets with 2D and 3D shapes.

Practice matching 2D nets to the 3D shapes the fold up into. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

[Free Registration/Login Required] Students will explore cross sections and nets of three dimensional objects. Click challenge me to answer practice questions and click learn more to watch a video.

Use this tool to see animated models of over 100 different types of polyhedra. There are five options for how they appear, and you can also see the net, 'explode' the solid so that the faces are separated, or drag it to rotate it...
