Symmetry Using Squared Paper
Demonstrate a symmetrical picture on squared paper, showing the line of symmetry (see Photocopiable Sheet E). Revise with the children the facts and concepts pertaining to symmetry. Give children copies of the picture and ask them to fold it down the line of symmetry, demonstrating that each side is, in fact, a reflection of the other. The following activities will help the children to understand the concept and appreciate the need for accuracy.
