This site gives a short interactive quiz which allows students to self-assess their understanding of the concept of dilations.

[Free Registration/Login Required] Observe what happens to volume as pressure is changed, and then answer a challenge question after the activity.

In 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...

In this activity, students will explore the properties of rotations and the relationships between the original and image figures.

Using Cabri Jr. and the properties of rotations to get a true understanding of how a figure is rotated about a point.

It is important for students to know what happens to the coordinates of points when they are translated in the coordinate plane. This activity enables students to use Cabri Jr. to develop this understanding.

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

Test your knowledge of rotation of shapes and determing the center.

Test your knowledge of rotation of an object and determine the center.

[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.

[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...

A basic definition of what rotation is at this site from MathWords.com. Provides a diagram to illustrate the concept. Links to other related concepts included.

Explore different ways of proving some theorems about lines and angles. Some transformations are used. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

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.

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.

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.

Think about the surface area of a cube. At this one page website, you use that information to complete the challenge. Solutions are offered right at the website.

Reflect any point, line segment, triangle, or any other figure over one or two lines using this dynamic applet. Points and lines are entered by point-and-click rather than by typing equations or ordered pairs. A very neat exercise to...

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...

Oswego City School District provides a three link tutorial on dilations. By clicking on each of these links, you will find the definition of a dilation, examples of dilations, and a quiz to test your skills.

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

At the Food Market there are a lot of shapes. Help Afia find and name the shapes.

A definition and examples of point symmetry, as well as links to information on rotational symmetry, reflection symmetry, transformations, and rotation.

Explains how to perform a rotation using an interactive tool and presents problems to try. Includes a video example. [1:25] Hints are available for the problems.
