Exploring turns

A lesson plan for grade 4 Mathematics
In this lesson, students explore the geometric transformation of rotation. They create a design and 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.
