In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying...

[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.] The video describes how to determine what shapes are used to create a given composite shape. The video is followed by practice problems.

Practice your knowledge of all possible cross-sections of common 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this activity, 2nd graders will identify shapes found around the room by recognizing their attributes such as number of angles, vertexes, and faces.

This program simulates a particle connected to an anchor by a damped spring in two dimensions. Try changing the initial settings.

This is the analog of Green's theorem, but for divergence instead of curl.

Match graphs with the correct scenario for the projectile motion by understanding velocity, acceleration, and displacement.

Practice problems dealing with displacement, velocity, and acceleration vectors for horizontally launched projectiles. In these practice problems, students will compare initial speed and time in the air for multiple projectiles.

Learn about how things fly through the air.

An applet activity that provides an exercise in working with perimeter and area of 2D objects. The user is given a random figure and allowed to enter a value for the area and perimeter. Use the "How" and the "Why" button to assist you....

This task challenges a student to demonstrate understanding of the attributes of two-dimensional shapes.

This task challenges a student to use knowledge of geometrical attributes to identify and describe shapes.

This task challenges a student to demonstrate understanding of the concept of two dimensional shapes and their properties.

This task challenges a students knowledge of 2-dimensional geometrical shapes to sort shapes and to design a shape that has a given set of attributes.

At the Food Market there are a lot of shapes. Help Afia find and name the shapes.

This resource allows users to test their geometry knowledge.
