[Free Registration/Login may be required to access all resource tools.] In this tutorial, students learn about the rules that operate in the rotation of 2-D figures on a coordinate grid. Includes video, lots of examples, review...

In this activity, students will investigate the relationship among the three types of rigid transformations - translations, rotations, and reflections.

[Free Registration/Login may be required to access all resource tools.] This concept explores graphing a dilation given a description of the dilation. Students examine guided notes, review guided practice, watch instructional videos and...

The objective of this lesson is for learners to, "explore spatial relationships by determining the area of various shapes and creating tessellation patterns." Using a variety of hands-on activities, students apply concepts of geometry,...

[Free Registration/Login Required] Students will adjust Frankenstien's face to explore dilation. Click learn more to watch a video and click challenge me to answer a practice question.

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...

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

A rigid motion of the plane is a map of the plane to itself which preserves distances between points. The purpose of this task is to use fixed points as a tool for studying and classifying rigid motions of the plane, i.e., translations,...

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.

This site from Stanford University is on the topic of simultaneity in relativity.

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...

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.

In this set of questions, students practice using an interactive tool to reflect images on a Cartesian grid. Includes hints.

Lesson and activities focusing on line reflection. Here you will find a detailed explanation of the concept with picture examples, opportunities for interactive practice, and supporting classroom activities in the teacher resource pages.

[Free Registration/Login Required] Observe what happens in the change in the type of energy during a reaction in this simulation. After the activity, answer a self-correcting challenge question.

Middle schoolers are introduced to translations, reflections, and rotations and how to explore them in real-world scenarios.

Find the reflection that maps a given figure to another and draw the image of a reflection. The lines of reflection in this exercise have a wide range of slopes.

Over two dozen links are provided at this MathWorld site. From Polynomials and Series to Dynamical Systems and Catastrophe Theory, each link provides in-depth explanations and relevant diagrams of the topics at hand.

Use the activity center in TI-Navigator to discover a generalization for translating ordered pairs in a coordinate plane.

For this task, students are shown three unit squares and two line segments connecting two pairs of vertices. They are asked to find the area of a triangle formed by intersecting lines. They can solve it using coordinate geometry or...

[Free Registration/Login Required] This flipchart guides the students through the process of determining the volume of a cylinder. Students learn to transform formulas in order to find the missing elements.

Determine the meaning of dilation through the glossary entry.

Check your understanding of the definitions of geometry terms in this exercise. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.
