Bursting with introductory activities to symmetry and tessellations, this book also includes reflective images, anti-symmetry, and rotational symmetry.  Other activities enable students to independently create their own tessellations.  Many activities are based on or inspired by the art of M.C. Escher.  Classroom application requires that each pair of students have a set of three 3½" x 2¼" plastic mirrors available from ETA/Cuisenaire.  Book includes a sheet of 11" x 17" dot paper.
