The middle schoolers will find the area of each two dimensional figure on a net of a square pyramid. In groups, students will cut out the net and create a square pyramid. Groups will then discuss how to find the lateral area and the...

This hands-on instructional activity uses exploration and discovery to help young scholars determine the coordinates of the vertices of various figures when translated, rotated, or reflected in a coordinate plane. The exploration phase...

Explore this awesome tool that animates a robot that contains sliding arms (like those used in hydraulics) and rotating arms like those used in rotary motors. The exploration asks students to consider how to find the area drawn by the...

This teacher's guide from Public Television's Newton's Apple discusses and illustrates the physics principles governing the flight of a frisbee. Includes teacher lesson plans, activity ideas, discussion questions, and information about...

Simulation of a Lorenz attractor which is shaped like a butterfly. Manipulate the image and observe from all sides as the orbits about two fixed points are drawn.

Lesson providing practice for finding the perimeters of polygons. Students draw polygons using sidewalk chalk and then measure the perimeters of each shape.

This lesson will help young students understand the shape and movement of bubbles. Students will predict, practice, and record results as they blow bubbles with different-shaped objects.

This activity focuses on the various ways to construct the different types of triangles such as isosceles, equilateral, right, and right isosceles triangles. Students will begin by constructing triangles based on a minimal definition of...

In this activity, students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They then use the patterns and the calculator to predict the perimeter of a specific shape in the sequence.

Based off of the hit television show NUMB3RS, this lesson is more about student prediction and reasoning than actual formal math. In the lesson, students are to propose the shape that would be formed by a point on a bicycle tire, while...

This set contains questions regarding the Central Limit Theorem. The student sees that, as the size n increases, the shape of the sampling distribution gradually approaches a normal curve, and its population standard deviation decreases.

Students will compare areas of different polygons with a fixed perimeter and find the shape that gives the maximum area

In this activity, students observe a special characteristic of the bisectors of the angles in a triangle. They test their conjecture by changing the size and shape of the triangle.

In this activity, students will determine the average speed of a falling object. They will observe whether or not changing the mass and keeping the same shape have an effect on the average speed of the object.

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...

Students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They will then use the patterns and the calculator to predict the number of blocks it will take to build a specific shape in the...

Here the life of the Doukhobour culture in British Columbia is discussed. This Russian emigre pacifist sect and their communal way of life helped shape the debate over human rights in British Columbia.

Do you know what shape the state of Idaho is in? Come and check out the Library of Congress' site to find out fun facts. What does the word Idaho mean in Native American language?

Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.

Young scholars will learn the concept of volume by determining the amount of sand that is needed to fill the long-jump pit at their school (or any rectangular- or square-shaped container). This lesson plan will explain the importance of...

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 find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.

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.

Based off of the hit television show NUMB3RS, this lesson introduces students to pursuit curves, in which objects follow seemingly awkward paths due to other objects chasing it. In this lesson (which is technology intensive), students...
