Can you help Wally the wizard practice some of his tricks while you learn about symmetry and 2D shapes?

This lesson focuses on symmetry including reflectional symmetry, rotational symmetry, and palindromes. It defines each, gives examples, and practice activities.

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

This lesson focuses on symmetry groups; some shapes have more than one symmetry. You can add two symmetries to form a new one. It provides examples and practice exercises including a "symmetry calculator."

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...
