The young scholars will find the area of each two dimensional figure on a net of a rectangular prism. In groups, students will cut out the net and create a rectangular prism. Groups will then discuss how to find the lateral area and the...

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

A collection of circular objects will be used to explore circumference and diameter of circles.

This lesson allows students to discover the number Pi. By measuring real life objects, students will get to see where the number Pi comes from as well as how the circumference formula is derived.This lesson plan was created as a result...

Young scholars will calculate the diameter, circumference, and ratio of a real world object. Students will create an electronic slideshow to illustrate the process of determining the diameter, circumference, and ratio of these objects.

Create regular and irregular polygons and determine the angles and side lengths with this interactive exercise. Use Safari or Chrome browser.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

In this lesson make a spinning top to explore the concepts of shape, color, spinning, and optical illusions.

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....

Students practice interpreting scale models, receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this lesson make a tangram and experiment with it to make new designs and pictures.

Defines polygons and explores characteristics, types of polygons, and how to calculate the area of a polygon.

Discusses the radius, diameter, circumference, and area of a circle.

Practice identifying lines of symmetry on shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
