This problem will engage children as it can be done
practically. It is a good opportunity for talking about ways to
work systematically.
Key questions
Which ways of folding have you tried so far?
How will you remember what you have done?
How will you know when you have got all the ways?
Possible support
It would be helpful to have lots of bits of scrap paper for
children to fold. They can then use a new sheet for
each new fold which will allow them to compare the different ways
more easily.
