Paper Aeroplanes- Measurement

In Maths we have been learning about measurements. We have been learning how to estimate and measure. I made a paper plane. My Teacher marked out runway with a measuring tape.First I had to estimated 10m it actually flew 7m. My second throw I estimate 7.5m it actually flew 7.4m. I found it hard to make the paper plane because  I have not made a paper plane in like 2 years. I found it easy to fly the plane and I loved the maths activity.I enjoyed the hole thing excepted from making the plane.
