Teachers might find the complete Symmetry Topic List useful.
This topic covers line symmetry and rotational symmetry. The innate appeal of symmetry can be found in our reactions to finding symmetry in natural objects, such as precisely formed crystals or seashells. Symmetry in art is another source of delight.
Understanding the mathematics of symmetry is the focus of this topic. Accurately drawing the reflection of an object requires an understanding of the relative positions of reflected points. Defining the position of the mirror line is important to find the position and orientation of the reflection.
The Wrapping Paper lesson starter makes it clear that for rotational symmetry, the position of the centre of rotation is very important.
Work on this topic can produce some excellent display work!
