Geoboards are great for exploring shapes- how they are formed and how they work together. Most elementary classrooms have geoboards included in with their math supplies.

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.”
