Why do this problem?
is a simple example for pupils to explore routes. It allows pupils to develop persistence in trying to find more and more routes.
Tell me why you chose that way.
Can you find another route?
Are your routes all different from each other? How do you know?
How will you record your routes?
Some younger pupils will appreciate doing this activity "live" on a large scale with the children acting as the snail and the possible paths drawn on the ground.
