Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Learners examine the properties of quadrilaterals from the point of view of rigid motion. Different types of quadrilaterals are characterized by their symmetries, so learners explore the symmetries of a described quadrilateral to...

Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.

A definition and several examples of rotational symmetry. View two animations showing types of rotational symmetry, as well as real-life examples, including a dartboard and Ferris wheel.

An applet is used to explore the rotation symmetry of geometric shapes. [Requires Java.]

An applet is used to investigate the rotation symmetry of regular polygons.

This is a good site for elementary teachers to help educate students about symmetry by using pattern blocks. This link has multiple activities that the instructor could use including technological and standard activities.

Use this internet lesson to explore different types of symmetry in nature. Learners examine line symmetry, rotational symmetry, and bilateral symmetry. An integrated math, language art, and art lesson. Acrobat Reader required.

The learning activity explores symmetry. Students combine mathematics and art as they investigate reflection and rotation symmetry.

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

This is a site from the Math Forum that gives visual examples to show the differences between the four different kinds of symmetry. Examples are given along with links to additional information.

A unique geometry project that asks students to complete a transformation using a picture. Project includes instructions, examples, and quiz questions.

Students learn about symmetry. Topics explored are reflection, rotational, and point symmetry. Examples and definitions are included.

What lowercase letters read the same both upside down and right side up? If you have the answer, then you can handle this geometric symmetry math challenge. A one-page activity from the NTCM Math Challenge for Families collection....
