This lesson focuses on symmetry in physics. The laws of nature are the name given collectively to the physical rules (usually expressed as mathematical equations) that try to explain everything we observe in the universe.

Mr. Watkins asked his students to draw a line of symmetry for a circle with center $O$ pictured below: Aligns with 4.G.A.3.

This lesson plan deals with tessellations and their geometric concepts. Upper elementary and middle school students will also explore polygons, symmetry, analyze patterns and explore the role of mathematics in nature and culture.

Students learn to use pattern blocks to build a design that has a line of symmetry. They use the calculator to determine the value of half the design. They predict and then find the value of the entire design.

Assemble jigsaw puzzles of items in nature, engineering, math, and art that display symmetry. You can customize a puzzle's rows, columns, and piece shape to make the jigsaw challenging or simple.

Suppose C is a circle with center O. Find all lines of symmetry of the circle and explain why the list is complete. Aligns with G-CO.A.

Students will explore symmetry through a variety of learning games.

A simple explanation of the development of three principles of symmetry: parity, time reversal invariance, and charge conjugation.

Here is a site that clearly and thoroughly explains the symmetry of even and odd functions and how to test for these types of symmetry. There are example problems solved, problems for the student to attempt, and answers to the student...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to identify where a line of symmetry should be and whether a 2D shape has a line of symmetry. Includes video...

Analyze various shapes according to their reflective and rotational symmetries. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to state whether the given 2D shapes have line symmetry. Includes video demonstrating a sample problem [1:14] and a set...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to state how many more squares on a grid need to be shaded in order to give a shape line symmetry. Includes video...

In this lesson plan, learners will consider Symmetry in Sir Gawain and the Green Knight. Worksheets and other supporting materials can be found under the Resources tab. This lesson plan explores symmetry in the structure and themes...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to determine whether or not a shape has rotation symmetry.

This lesson focuses on wallpaper groups. While there are infinitely many possible patterns, they all have one of just 17 different symmetry groups. These are called the Wallpaper Groups. Every wallpaper group is defined by a combination...

Find out how animal body symmetry helps organisms survive.

Explore reflection symmetry in some different shapes.

Find out about the ways to name rotation symmetry: order, fraction of a turn, and angle.

Practice drawing lines of symmetry and creating symmetrical figures.

[Free Registration/Login may be required to access all resource tools.] Identify line, bilateral, and rotational symmetry.

Oxford mathematician, Marcus du Sautoy, presents a brief look of the invisible numbers that unite all symmetrical objects as he discusses prime numbers, symmetry groups, higher dimensions and other stumpers. [18:20]

This intuitive explanation shows how to determine if an object has point symmetry. The site offers examples of objects with point symmetry.

Students will watch a slideshow about the body symmetry of animals. Included is a short quiz of animals and images. The students will determine the symmetry of each animal. Students then design their own animals. They should design one...
