Measuring with Trundle Wheels

Yesterday on the 26th of May, Our whole class went outside, to measure with the trundle wheels. We hadto measure the lines on the FFG. We had to form five groups. We all had either 3 or 4 people. First, we had to draw a table in our Maths Book. Then we would write what we were measuring, then write down our estimations. Most of the people did the same things. There were: Two square court perimetre, Blue circle, runnig track perimetre.... In the end we all compared our results. And those numbers were quite big....
