Worksheet where students will attempt to measure the circumferences of circles using string and ruler. Hopefully leading to students spotting the link between Circumference and diameter and leading in to a discussion of Pi.
Starts with students using a ruler to measure perimeters of polygons - ensuring they can measure accurately with a ruler which is a skill some students lack confidence in.
Then students are posed the question of how to measure curved lines like in circles. Eventually lead them to using string and then in pairs students have to measures the circumferences which is always a fun challenge.
I print these as A3.
