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...

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

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

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.

[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.

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.

In this exercise, students practice finding the surface area using nets. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Practice using the net of a 3D figure to find surface area. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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...
