I like to walk along the cracks of the paving stones, but not the outside edge of the path itself. How many different routes can you find for me to take?
A little mouse called Delia lives in a hole in the bottom of a tree.....How many days will it be before Delia has to take the same route again?
If you count the number of pathways to and from each tree, what can this tell you about the dog's route?
