Age 7 to 11 Challenge Level:
One way to begin this challenge might be to see how many fence routes you can find by always starting in the same place.
You could use some blocks or cardboard boxes to represent the buildings, and lay them on the floor or on a table. Then you could use string or ribbon to show the route of the fence. You could draw your different arrangements, or perhaps take some photos.
