Illuminations: Exploring Turns

This lesson encourages students to explore the geometric transformation of rotation.

Students create a design then, using turns, make a four‑part paper “mini-quilt” with that design as the basis. While the formal term is rotation, the more informal turn is used at this grade band. The experience focuses students’ attention on the changes the geometric transformations make in a student-designed quilt square.
