In this 2-D shapes lesson, kindergarteners review plane shapes attributes. They engage in a shape hunt in the classroom and create art using plane shapes. A good, hands-on lesson!

Compare and classify 2-D shapes! Kindergarteners inspect the attributes of plane shapes and examine shapes in everyday life. They label the circles, squares, rectangles, and triangles they find. This is the website where you can find the...

Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Is it a calendar? A religious symbol? A political statement? One thing for certain is that Aztec sun stone designs remain an important symbol in Mexican cultural art. Young artists craft their own Aztec Sun design incorporating ideas...

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

In this exercise, students practice applying the properties of shapes. 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 classifying various two dimensional shapes as rectangles, squares, circles or triangles.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on classifying rectangles, squares, circles and triangles.

This tutorial provides illustrations for regular 2-D shapes as well as a definition for polygons and for regular polygons.

Classify shapes based on pictures or attributes, such as angle types and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] The video describes how to classify a real-world object as a circle, triangle, square or rectangle. The video is followed by additional practice problems.

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.

User will drag the vertices of the quadrilaterals to decide on the best possible classification.

This interactive diagram focuses on sorting polygons by common properties and then you select the correct label for each section of the Venn Diagram.
