Thinking It Through - Problem solving in maths

How could we order ourselves from heaviest to lightest, without using scales?

First idea - throw some rope over the basketball hoop and haul people up to find the heaviest and lightest 
(but we decided that wouldn't be safe).

Second idea - jump off something high and the person who lands first is heavier

Guess what - we landed at the same time!

We talked about balance scales, and someone thought about using a seesaw. 
So off we went to the play-park just down the road.

We had solved the problem!

What other ideas could we have tried?

    We were really surprised to learn that your teacher and the child reached the ground at the same time. We wondered why that might be. We
    thought that using a see-saw was a great idea. We don't have a see-saw in Clyde.
