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

This resource provides information about symmetry, and everywhere it can be found.

[Free Registration/Login may be required to access all resource tools.] Find a figure's lines of symmetry.

In this lesson, 3rd graders first examine images and decide whether they are symmetrical or not. Next, they create individual symmetrical shapes with their bodies and identify the line of symmetry present during these shapes. They then...

This presentation provides a tutorial on symmetry. In the tutorial, you will do the following: learn about geometric symmetry, explore line or reflection symmetry, explore rotation symmetry, and explore translation symmetry and frieze...

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.

Use these interactive activities to explore symmetry.

Students will play interactive games and explore symmetry.

In this lesson students will learn about line of symmetry in real life objects. An interactive web lesson is used to engage students and give a multitude of real life examples with some interactive practice. The lesson also includes an...

[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...

Looks at the lines of symmetry in different types of polygons. Includes ten practice questions. Each question is accompanied by an explanation of the answer.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to identify the lines of symmetry in letters of the alphabet. Includes video demonstrating a sample problem [1:27] and a...

Explains symmetry about a line, using animations to illustrate the "rotation" or "reflection" involved in this type of symmetry.

Introduces the concept of symmetry by learning the definition, types, lines of symmetry, and point of symmetry. Check-out the solved examples for better understanding and try your hand at solving a few interactive questions at the end of...

Brush up on your math skills relating to lines of symmetry then try some practice problems to test your understanding.

The division of triangles into scalene, isosceles, and equilateral can be thought of in terms of lines of symmetry. Aligns with 4.G.A.3.

This tool allows you to see a face with perfect symmetry. You can upload photos and it creates a symmetrical image. A great activity to do with students, and great for a bulletin board display. [Requires Java.]

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

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...

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.

An introduction to the various types of symmetries that can occur in the graphs of functions. Uses vertical, horizontal, and oblique reflections as a means of recognizing symmetries.

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.

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.
