Students often classify objects by size and shape. Now they will look more at the properties of objects such as hardness, flexibility, and texture. Included in this lesson plan are examples of student's science journal entries, a video...

[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.

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

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

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.

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.

Learn about the properties of 2-D shapes: circles, triangles, polygons, and quadrilaterals. Includes information, video, and examples about each, with games and quizzes for reinforcement.

[Free Registration/Login Required] With this flipchart students will learn how to classify two-dimensional shapes and discuss the attributes of polygons.

[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.

Identify the shape that is given in word form to advance your kangaroo to the finish line.

At this site from The Franklin Institute you can practice classifying objects according to physical structure and characteristics.

Did you know that two-dimensional shapes are also called polygons? This lesson describes the various 2-D shapes and includes two interactive games to reinforce skills.

Sorting activities are the perfect way to help children learn to classify their world from the start. This article explains why this skill is so important in the "real world" and contains a list of sorting activities for preschoolers.

Students will be sent ordered pairs through lists using the TI-Navigator. These pairs will then be graphed as a line graph and students will classify the shape of the quadrilateral and justify their choice.

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

Describes, with illustrations, the basic two-dimensional shapes students will encounter in elementary Math.
