[Free Registration/Login may be required to access all resource tools.] Recognizing and identifying rotation transformations and rotational symmetry

A collection of puzzles that will challenge your knowledge of measurement, logic, symmetry, numbers, algebra, and other math-related topics.

Dr. Math, in a reply to a student's question, explains how to find the location of the vertex and focus, calculate the distance between the focus and vertex, as well as identify the axis of symmetry and the directix.

Understand how the momentum of an object remains constant if there is no outside force involved. Examine translation symmetry. The article is wrapped up with a collection of homework problems to solve.

In this activity, students will identify and record ordered pairs from a coordinate plane. They will examine symmetry about the axes, reflections, and symmetry in nature. They understand geometric concepts like area and perimeter, and...

Site provides information and activities on various aspects of geometry, from shapes to patters and symmetry. Make your own tetra puzzle or build an icosahedron in the classroom. Interactive and fun.

Students learn to use pattern blocks to investigate symmetry by building a design, making its mirror image, and using the calculator to determine the value of both the design made and its reflection.

In this activity, students use the drawing and measurement tools of Cabri Jr. to blend coordinate geometry with drawing tools. They visualize symmetry and reflect a point across the y-axis.

In this activity you can learn the geometric and algebraic meaning of the symmetry about any point and any vertical axis.

In Spanish. This is an approach to the concept of free vector and its coordinates, calculating translation and symmetries of simple figures.

In Spanish. In this unit you can learn about movements in the plane: translations, symmetry and rotation.

An interactive site that explores the elements and principles of visual art through the artist's toolkit. This is the encyclopedia entry for balance which covers symmetry and asymmetry, balance with color, and other types of balance.

Interactive figures to learn about symmetry and translation. [Requires Java.]

Students show comprehension of advanced mathematics skills in Geometry. The questions check understanding on transformational geometry. Topics include translations, symmetry, and rotations.

During the Olympic and Paralympic Games many national flags will be on display. This activity explores 2D shapes, angles and symmetries in the context of flag designs, and is designed to be accessible to primary pupils at Key Stage 2.

[Free Registration/Login may be required to access all resource tools.] You're probably familiar with starfish and sand dollars. They are both echinoderms. Sea urchins and sea cucumbers are also echinoderms. What's similar between these...

Try to find the line of symmetry of these 8 figures. If you find it the two figures should coincide.

Students use pattern shapes to explore geometry and fractions, creating their own designs, or filling in outlines. As they work with the shapes students explore geometric relationships, think about angles, investigate symmetry, and...

[Free Registration/Login Required] Angles and symmetry are reviewed in this learning game. Students try to identify high-scoring paths by slamming the ball off the sides of the game board and send it on a path that collects the most tokens.

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

Origami (ori-folding, kami-paper) is the traditional Japanese art of folding paper. Students will discover relationships between shapes as they are actively engaged in this hands on geometry lesson to learn basic geometric shapes, their...

If you want to plant a class garden, this is a great resource for combining geometry, Native American studies, and rocks.

Here, at this site from the Arizona State University, is a simple lesson plan for math or art teachers in the primary grades. Students create their own symmetrical design based on Pennsylvania barn signs. Also has a link to a site with...

The Committee on Elementary-Particle Physics, part of the U.S. National Research Council, presents this massive report on particle physics. It's a definitive document. Surprisingly readable, totally detailed. Start with the Table of...
