The students will explore angles, rays, line segments, perpendicular lines, parallel lines, and two-dimensional figures through the use of the book Shape Up! Fun With Triangles and Other Polygons by David A. Adler. They will also...

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.

Describing 3D shapes in Pre-K and Kindergarten is now an expectation as it is a key geometry standard. This resource contains 3D shapes activities and resources for practicing this standard. Included are chants, videos, games, poetry,...

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

In this lesson on shape attributes, students learn key vocabulary, explore bases, and apply their learning to a real-world situation.

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 learn how to apply geometric properties and relationships to describe, compare, and draw two dimensional shapes.

[Free Registration/Login may be required to access all resource tools.] Students practice classifying various two dimensional shapes as rectangles, squares, circles or triangles.

Analyze various shapes according to their reflective and rotational symmetries. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Analyze various shapes according to their reflective and rotational symmetries.

You will enjoy this shape game. It tells you the name of a shape and all you have to do is click on the correct shape. If you get confused you can have another try.

A math challenge where geometry, measurement, and problem solving meet. Explore the properties of three dimensional shapes when you discover how six friends can equally divide a nine inch square chocolate cake. A one page activity from...

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to predict the next shape in a two dimensional or three dimensional pattern.

In this lesson, 7th graders slice three dimensional objects to determine what two dimensional shape is created.

This site provides an in-depth definition of a two-dimensional figure and a three-dimensional figure. Related terms include arcs, vertices, polygon, and many more.

The purpose of this task is for students to compose two-dimensional shapes to create a composite shape using tangram pieces. The teacher will read "Grandfather Tang's Story" and the students will use tangrams to compose the animals from...

This lesson describes three dimensional shapes and provides two interactive practice activities.

For this lesson the children will demonstrate parts of a whole using a candy bar (or fruit), and piece of paper. The activities are used as instructional plans to help students better understand shapes and parts of a shape up to a whole....
