Analyzing designs

A lesson plan for grade 4 Mathematics
In this lesson, students explore the geometric transformations of rotation, reflection, and translation. They create a design and then, using flips, turns, and slides, make a four-part paper “mini-quilt” square with that design as the basis. This experience focuses students’ attention on both the changes produced by the geometric transformations and on line symmetry.
