Students understand what a closed shape is and identify different shapes in the environment by name.

[Free Registration/Login may be required to access all resource tools.] The video defines a composite figure and describes how to determine how many triangles are within the given composite shape. The video is followed by practice problems.

[Free Registration/Login may be required to access all resource tools.] Students watch a video to determine if a two dimensional shape can be tessellated and then take a quick assessment to test their skills.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to match a given shape with those that are equivalent or the same type. Includes video demonstrating a sample problem...

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.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are shown a composite figure and must identify and count shapes within it. Includes video demonstrating a sample problem [1:27]...

Sixth graders take their knowledge about area of rectangles, squares and triangles and apply it to parallelograms, trapezoids, and composite shapes.

Second graders will be able to identify 2-dimensional shapes and tell the number of vertices and sides.

In this activity on 2D shapes, 3rd graders will learn to discriminate quadrilaterals from other polygons. Additionally, they will be able to identify attributes of a square, rectangle, and rhombus.

Learn how to manipulate and measure composite shapes.

How can you describe the pattern made by a growing triangular shape? This interactive exercise focuses on using what you know about pattern recognition and completing a table so you have data you can use to graph the coordinates on a...

Identify and graph corners on shapes graphed in the first quadrant of a coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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.

A guide to support parents as they work with their students in angle measure and plane figures.

A guide to support parents as they work with their students with two-dimensional and three-dimensional shapes.

In this activity, students describe how to move a shape from one place to another in a plane. They learn about translations, rotations, and line reflections. [Requires Adobe Reader.]

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...

Explains the basic concept of the area of geometric shapes with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

Given a figure on the coordinate plane and the definition of a rotation about an arbitrary point, manually draw the image of that rotation.

Given a figure on the coordinate plane and the definition of a rotation about the origin, manually draw the image of that rotation.

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.

[Free Registration/Login Required] The teacher will use this lesson plan flipchart to review geometry plane figures.

[Free Registration/Login Required] Students will learn the 6 solid figures and characteristics, including face, edge, and vertices. Students will learn the plane figures when looking at the solid figures. Students will then take a 10...

The introductory pages introduce the shapes and their attributes: triangle, rectangle, square, rhombus, circle, and oval. The additional pages allow students to practice shape recognition, tracing shapes, and drawing shapes.
