Geometric sorting board: a diy hack

geometric sorting

We’ve had this geometric sorting board for a while, and I see it around the web fairly often in Montessori circles. In the past six months (from about 20 months on) I’ve occasionally offered it to Jasper, who over time has enjoyed exploring the shapes, pointing out the colours, and hanging the shapes randomly from the pegs. The idea that certain shapes would fit together on particular pegs wasn’t really happening, even with modeling.

Then I remembered this post from the awesome German-language Montessori blog: Eltern vom Mars.

It’s the simplest solution in the world: tracing each geometric shape onto the board.

I used pencil so that down the road, we can raise the stakes by erasing the shapes. Immediately this has become one of Jasper’s most-often used activities, and paired with this four-section basket, it also provides opportunities for sorting by shape or colour. It’s such a simple hack, and I can’t believe it took me this long to remember it.

I can’t remember where our geometric sorting board came from — I know it was second-hand, either from a store or a friend — but you can find something very similar here (that set actually looks a bit chunkier and would be easier for a young toddler to use).

If you’re worried that this might make it too easy, I’d say observation is your friend. If the child is focused and engaged with the work and is drawn to it over and over, then it’s just right. When the time comes that Jasper is losing interest, I’ll probably put it away for a while, and then reintroduce it on our shelves with the pencil lines erased.
