Symmetry possibilities

For most ages you can start with mirror puzzles (and I am willing to loan you my book to make copies of other puzzles if you sign in blood that you will return it). From there you can go to line and rotational symmetry and do some of the things in the book, or do something like §17.1 LE 17, which is all about line symmetry.

Or you can take children on a “Symmetry Walk” around the room (small children; bad weather) or around the neighborhood (any size children, good weather)

Or you can do some paper-folding and cutting activities, but make sure they retain cognitive demand (for instance, showing a design you have cut after folding the paper in four and get them to try to duplicate it)

There are other possibilities – check with me if there is something you would like to use.
