This tool allows you to manipulate various geometric solids and investigate their properties.

Students will use their knowledge of plane figure attributes to create and view shapes by cutting and rotating shapes to stimulate discussions on names and attributes of various shapes they do not regularly encounter.

Shapes is a fun educational activity to help children learn basic properties of simple geometric figures. Children will practice looking for differences and similarities between shapes to complete puzzles. Shapes! gets progressively more...

In this lesson, students will identify 2- and 3-dimensional shapes as well as create shape drawings and sculptures. Teacher materials are available.

Given a figure on the coordinate plane and the definition of a rotation about an arbitrary point, draw the image of that rotation. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video,...

Given a figure on the coordinate plane and the definition of a rotation about the origin, draw the image of that rotation. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...

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

Young scholars will identify objects as translucent, transparent, or opaque. Upon seeing the shadow of the opaque object, students will identify the geometric figure created by the shadow.This lesson plan was created as a result of the...

Print or create worksheets to assess students' understanding of geometrical figures and describe the relationships between them.

This is a hands-on instructional activity that will help students explore shapes in their environment. Students will work in diverse groups to complete this activity. Students will make a class book of their findings.This lesson plan was...

This site provides definitions of different types of polygons and figures.

There are many other sequences that are based on certain geometric shapes. These sequences are often called Figurate numbers, numbers that can be represented using geometric shapes. Examples include square, triangle, and tetrahedral...

In this lesson, students will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

Students reflect on their work and apply what they've learned about the characteristics of geometric figures. Includes a learning game to be played with a partner.
