When I was at primary school many moons ago, I loved the spirograph set that received as a Christmas present one year. This week in class I got my students to investigate what spirographs were and then they had to create their own great examples using a website link. Of course this was a little different to how we used to make them but fun none the less.
For those of you who do not know what the spirograph toy was it is a geometric drawing tool that creates curves using equipment similar to gears on a bike. It gave me hours of fun when I was young and this week in class my students enjoyed creating some wonderful examples.
