Symmetry

Geometry Reflect-View™

Teach the basics of geometry, including axes of symmetry, reflections, transformations, and congruence. Made of red acrylic, which enhances the reflective quality. 3-1/2" L x 6" H x 1-1/2" W. Grade K and up. More.

Geo-Reflector™ Mirror

See-through plastic surface with special reflective qualities allows students to gain an intuitive understanding of geometry, symmetry, and congruence as they view, move, and draw images. Grades 1-6. More.

MIRA™ Math Geometry Tool

This geometric tool has the reflective quality of a mirror, as well as a transparent quality to provide a fascinating new look at geometry. By placing the MIRA™ on any shape, children quickly see concepts of symmetry and congruence. It is also ver... More.

Hinged Mirror

Perfect for use with pattern blocks or other symmetry-related manipulatives. Each mirror measures approximately 3" x 5". More.

Geometry MIRA™ Math Activities for Elementary School

Looks at geometry through a child’s eye. The many illustrated games and puzzles use the MIRA™ to introduce concepts of symmetry, congruence, parallel and perpendicular lines, angles, and other ideas. 85 pages. Grades 3-8.

Geometry MIRA™ Math Activities for High School

A beautifully-sequenced review of transformational geometry with the MIRA™, starting at a 7th grade level and moving upward. Includes plenty of activities for junior high students. Topics include properties of perpendicular lines, reflection, ... More.

KnoTiles™

Everyone is familiar with the utilitarian and decorative uses of knots, but mathematicians study knots as well. KnoTiles™ is a puzzle that serves as an introduction to the mathematics of knots and symmetry of knot designs. All of the knots through... More.

Geometry MIRA™ Activities for the Senior Grades

Every time a student uses a MIRA™, the concept of bilateral symmetry is invoked. This allows the student to progress from bisecting angles, drawing perpendiculars and parallel lines in the middle grades, to drawing the conic sections and even to i... More.

Geometry MIRA™ Activities for the Junior Grades

The activities in this book use the MIRA™ to investigate the role of bilateral symmetry in geometry. Exercises are designed to help students discover spatial relationships, recognize geometric shapes, and prepare for further geometry concepts when... More.

Geometry MIRA™ Activities for the Middle Grades

The exercises in this book will provide students with a foothold on informal geometry. In each exercise, the student is asked to construct a simple geometric figure, to guess (or conjecture) its properties, and then test the guesses. Once students can r... More.
