'Take One Metre' printed from http://nrich.maths.org/
Use about 1 metre of paper (for example from a paper roll) and cut it into a few different lengths.
Lay each strip out flat.
How long is each strip?
If two are the same length can you cut them again to make different lengths.
Measure each length as carefully as possible.
Find a way of recording all the lengths of the pieces that you have made.
