In December, it's fun to decorate for the holidays. This lesson includes 2D shape and counting practice!

Guide a mummy safely through the burial chambers of a pyramid as you solve length and area problems in basic to advanced geometry. There are four game zones that deal with circles and triangles, quadrilaterals, the Pythagorean Theorem,...

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.

At the Food Market there are a lot of shapes. Help Afia find and name the shapes.

This task challenges a student to demonstrate understanding of the concept of two dimensional shapes and their properties.

Use this rhyming description of Max's Fantastical Zoo to make some amazing animals from geometric shapes. There is a teacher's guide for easy lesson planning.

Identifying 2D shapes in common objects and sorting according to shapes connects the real world to learning shape names and attributes.

Use this site to practice identifying shapes, colors, and animals with these interactive games.

An interactive game to find number of edges, surfaces and vertices of different geometric shapes.

Cross-sections are one way that two-dimensional objects are connected to three-dimensional objects.
