[Free Registration/Login may be required to access all resource tools.] The video defines a composite shape and shows how to determine the total number of triangles in the given shape. The video is followed by practice problems to assess...

In this activity the teacher will send two lists, a window range, and an educational document via the TI-Navigator. Students will explore the reflections and rotations of a shape in the rectangular coordinate system.

In this activity, students' will use a pair of motion detectors to record the cartesian coordinates of a rod moving in a star-shaped pattern and calculate the distances moved between the vertices of the star. They also compare these...

[Free Registration/Login may be required to access all resource tools.] The video discusses a brief overview of circles, rectangles, squares, and triangles and helps students determine which shape is shown and why. The video is followed...

In this task, seven pennies are placed in a circle so that they are all touching one in the center and their neighbors. Students are asked to find as many rigid motions of the plane as they can which are symmetries of this configuration...

Sports such as hockey, football, basketball and tennis use balls of different sizes. Can you arrange a selection of different balls in a line each touching the next to make the shortest line? This activity offers opportunities for...

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.

The learners 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 total...

This lesson allows learners 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...

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.
