A pre-test contains questions about transformations that lead to congruent and similar images. It also covers angle relationships associated with triangles and parallel lines intersected by a transversal. 

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation....

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

Your algebra learners emphasize the"geometric" in geometric series as they use a common ratio between algebraic terms and find that it corresponds to a repeated similarity transformation. 

Your learners will write quadratic functions whose graphs include specific points and explore how these graphs are related to each other.

Your geometers are used to finding the perimeter of a square or rectangle, so give them something different this time! With this lesson, small groups will receive a picture of a shoreline and calculate the perimeter. The website listed...

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

Fourth graders visit a real pond. They mark the pond's curvilinear perimeter using string. They measure the string to find the actual perimeter of the pond.

Eighth graders measure in feet and inches and convert to explore the relationship between the converted measurements. In this measurement lesson, 8th graders use the whisker and box plot to represent the measurement of a cat. ...

Grouchy? Sad? Here's a great resource that shows kids how music can be used to lift their spirits. Kids collect and chart data on the effects of music on emotions. After analyzing the results of their experiment, they develop...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

When is not solving the expression the correct answer? When you are checking the understanding of a math concept that is not number dependent. The real question being asked here is to look at the initial number, fraction, mixed number,...

Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity....

Small groups work together to create a tower out of 15 pipe cleaners under a set of imposed limitations. First, restrict team members to use only one arm, and then remove the use of spoken language. There is also a time limit. The...

Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

Research various types of bridge designs. Your class will be asked to consider what it would be like without bridges while learning about how they work. They will construct a model bridge based on given parameters. They then calculate...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Students explore the concept of perimeter. In this perimeter lesson plan, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.

Students examine folk’s tales for Cause and Effect. In this literature lesson, students read "The Origin of Fire" and "The Origin of Medicine” and look for cause and effect. They use a TI Navigator to write down their findings.

High schoolers use materials from their own environment to design a kite. In this kite design activity, students research the history of kites and obtain a formal mathematical definition of a kite. High schoolers sketch kite designs...

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Eighth graders complete worksheets on reading the distance on maps in miles or kilometers. In this maps lesson plan, 8th graders use a calculator and ruler.

How can 5th graders show understanding that 30 x 225 is half of 60 x 225 without completing the computation? They can use an area model and draw it out. An array, or an open array, is an area model that allows for young learners to...
