Investigate the concept of symmetry at this test prep site. See detailed definitions and picture examples, answer the questions in the interactive practice pages, and do the classroom activity where students use a digital camera to...

This site defines transformation and lists several different examples of transformations. Be sure to follow the links to related terms, everyday examples, challenging problems, more information, and the interactive check point involving...

This upper elementary and middle school lesson plan explores tessellations and their geometric properties. Plenty of interactive support is available for students. Lots of resources for teachers to use.

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during...

Twenty-five problems cover the various transformational geometry topics in different settings. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...

Resize and rotate different types of quadrilaterals--square, rectangle, rhombus, trapezoid, and kite--while learning the definitions of these different shapes and labeling the angles and diagonals. CCSS.Math.Content.3.G.A.1 Understand...

Use this internet lesson to explore different types of symmetry in nature. Learners examine line symmetry, rotational symmetry, and bilateral symmetry. An integrated math, language art, and art lesson. Acrobat Reader required.

[Free Registration/Login Required] This is a visual instruction of tessellations. It displays a variety of tessellations throughout the world and in different cultures.

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

Students explore slides, flips, and turns in this interactive web lesson.

Young scholars will use a square to investigate other polygonal shapes that can be formed. Students will work with these polygons to make designs that will later constitute cooperatively designed quilts. The quilts will be made by...

You will have to use visualization to help you solve this challenge. At this one page website, you will be able to check your solution.

What lowercase letters read the same both upside down and right side up? If you have the answer, then you can handle this geometric symmetry math challenge. A one-page activity from the NTCM Math Challenge for Families collection....

This interactive activity gives you an opportunity to color in a tessellation that is different from the usual. Read the short introduction to find out more about this tessellation that doesn't repeat.

See if you can figure out which symbols are on which cube face at this one page website. The solution is just a click away once you have your solution in mind.

If you can visualize a cube and turn it around in your mind, then this is the challenge for you. This one page website has the solution available to check your thinking.

This activity is a based on an activity I saw in Exploring Geometry with the Geometer's Sketchpad. Student will construct a trapeziod and then use rotation to create a parallelogram from the trapeziod. The follow up questions lead the...
