[Free Registration/Login Required] This flipchart explains 2-D and 3-D shapes.

Students will complete a series of learning games to explore two-dimensional shapes, such as naming them and completing the shape.

Students will idenitfy and group shapes based on their attributes.

Drag and drop shapes into a puzzle to explore tessellations.

[Free Registration/Login Required] This flipchart is designed for an early childhood classroom and focuses on circles, squares, rectangles, and triangles. Opportunities provided for student participation include drawing plane shapes,...

A book about shapes in the world around us. Includes audio narration in 9 additional languages with text in English.

The resource consists of area formulas and diagrams for a variety of shapes.

Abeni works at the pyramids. Visit her and find out more about circles and triangles.

In this exercise, students practice identifying shapes on the coordinate plane. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

[Free Registration/Login may be required to access all resource tools.] Students practice counting sides and vertices in various two dimensional shapes.

Third graders develop their understanding of the importance of different 2-dimensional shapes by finding real world examples.

Explore the process that changes the shape, size or position of a figure to create a new image, transformations.

Find the area or perimeter of shapes like triangles, rectangles, parallelograms, and hexagons on the coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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

Practice combining shapes to make other shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Look at the properties of 2D shapes to see which shapes can belong to the same group. Includes hints.

Find the area or perimeter of shapes like triangles, rectangles, parallelograms, and hexagons on the coordinate plane.

[Free Registration/Login may be required to access all resource tools.] The video describes how to determine what shapes are used to create a given composite shape. The video is followed by practice problems.
