Arc Length

I made these for my Foundation year 10 class, We will look at Circumference again at the start of the lesson. They used IKEA tape measures to notice that the circumference was roughly ‘3 and a bit’ times the diameter. I’m hoping the class will be able to use the circumference to find arc length.
