An interesting historical finding, of a 1615(!) book on tiling in the context of glass designs. The book is replete with many simple, but attractive tilings, most of which I’ve not seen before! https://t.co/o1oxe8DXzx pic.twitter.com/JlgHMeBsDi

Week 8 of #MathPhoto23 is here!

Our focus is #units.

Where do you see composed and partitioned units around you? How do you see ‘How many’?

Take photos and share to Twitter using hashtags #MathPhoto23 #units.

I can’t wait to see what you find!#MTBoS #iTeachMath pic.twitter.com/6RhSmWeid7
