You can pick up geoboards at your local school supply store, find them on ebay… Or, if you are on a tight budget and have some scrap wood at home…make it yourself.
I happen to have a husband who is very handy at building things and has an ever increasing pile of scrap wood in the garage. He was happy to oblige when I presented the geoboard project to him.
How to make your own Geoboard:
– Cut a piece of plywood in a 10 x 10 square.
– evenly space 25 nails (my husband did screws because they would be more durable) in a 5 x 5 square.
That’s it! Give the board to your child with a handful of rubber bands for some open ended exploration.
We’ve talked about how you can start with a triangle or a square and stretch it to a rectangle or trapezoid or parallelogram, etc. The kids have really enjoyed playing with their boards- this morning, they turned them into “guitars” and made “beautiful music.”
