Measuring accurately to make 1 metre lengths if string

In Maths we were given a piece of brown twine. Mrs  Field asked us to use our 30cm rulers to measure and cut the twine into 1 metre and a bit left over. We had to work it out by ourselves and show how we added the measurements together. We all had a chance to check how close we were to a metre and Hunter was the closest with 1.02m. It was interesting to see all the different ways of getting to 1metre. 30+30+30+10 =100 was a common way to solve it. We also had 30+ 20 = 50 then fold it in half and double it.
