Tesselation with blocks

What: Tesselating and making pictures or patterns with blocks.

Several of the resulting creations, including some that come from putting blocks on top of each other. Note the flower stem is a two-layer pattern. 

How: I have no idea where we got these blocks – I played with them as a child, and it’s possible that my mum played with them as a child too. They are good manipulatives for starting to think about angles – many of the shapes fit together, in fact most – but not quite all. So you can easily spread a tesselating pattern out across floor space, working out from the centre. Or, you can just use them to make simple pictures, tangram-style. We did a bit of both. It held Kid 5’s attention longer than Kid 3, and I’ve played the blocks at younger ages too but this was the first time they really actively got into it and started manipulating the shapes themselves.

Extras: I think this is all in whether or not you want to start talking about the angles, how some corners are pointier than others, whether you want to look at the number of sides shapes have before and after you put them together, surface area, breaking up 360 degrees into equal parts, which shapes tessellate (and do you even want to say “tessellate” or do you want to say “fit together without spaces”, which I think is how it’s been put to Kid 6 in school).
