Paper Aeroplanes - Measurement

In maths we have been learning about measurement. I have been learning to estimate and measure. I made a paper plane. My teacher marked out a runway with a measuring tape. First I had to estimate how far my plane will go, I estimated 2.5m and it surprisingly went 2.5m. The thing that I found hard was getting a perfect launch, the thing I found easy was creating the plane. I enjoyed seeing all the different planes that were made.
