##
Observing Symmetry

- Have your students observe and analyze patterns in brickwork, pavements,
wallpapers around the school building or at home.

- Go on a "tessellation" walk. Tally which shapes tessellate and where.
(hint: check out tile floors, ceiling tiles, radiator vents, window grills,
roof tiles).

- Use a kaleidoscope to make and observe patterns (used reflection).

- Prepare a set of laminated grids through which to observe and analyze
patterns.

- Fold and cut paper to make patterns; notice how different folds may make
different symmetries.

- What kinds of symmetries and patterns can you find in the clothing you are
wearing?

- Using an overhead projector, arrange pennies so that the centers form a
square grid; arrange them again with tighter packing so that the centers form
a triangular grid. Have the students use the triangular grid to locate a
rhomboid grid, and a hexagonal grid. Are there any other ways to tight pack
the pennies? What are the implications of this for pattern-making?
