Reflection Symmetry - Indicator: Determine whether or not a given 2-D shape is symmetrical by using an image reflector or by folding and superimposing.
Demonstrating for students the symmetry of a 2-D shape using a transparent reflector is unique to other methods of teaching the same indicator. The images can be manipulated and viewed from a variety of angles to develop a strong understanding of concept and possibly misconceptions held by the students.
