A World of Symmetry: Math-Geometry
Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Symmetries of Strip Patterns
Students study strip patterns and identify symmetry. They create a paper doll chain. They experiment with different shapes. They determine if their chain is a strip pattern. They create snowflakes with triangles.
