Rotation Symmetry (Symmetry Part 4)

Rotation Symmetry (Symmetry Part 4) is a Grade 8 geometry hunt for rotational symmetry in nature and everyday objects. Students examine examples such as flowers and starfish, calculate angles of rotation from the number of repeating arms or petals, and then search for objects that match target angles such as 36 degrees or 60 degrees.

Use it as a whole-class application activity when students are ready to connect symmetry formulas with real designs. Questions about seven- or nine-armed starfish push students to calculate nonstandard rotation angles instead of relying only on familiar polygons.
