The resources in this unit are supportive in helping students understand the symmetry of shapes. For example, worksheet M-2 consists of the teacher creating a magnifying glass that students can use as a tool to investigate two dimensional shapes that already exist in their surrounding. The hands on approach to identifying two dimensional shapes is valuable.
