Tks all for the wealth of information!!
Come to think of it, I do have some tessellation stuff that I put away and will dig out again. The Learning resources ones and the Mathart ones are amazing, as are Escher.
Don Cohen's book sounds great too - DS loves algebra for the "language pattern", so this sounds like something he'd like in the coming years.
DS loves Lego and Knex, but not weaving so far. Actually, I'm the one making the potholders (From Klutz books), and I love it. What a good excuse to look at these - if he doesn't like it, I'll have a go at it myself *grin*.
Maybe these hols, we'll have a look at patterns in nature. Perfect weather for picnic and sketching in the park ...
Tks once again for the great ideas!!
