Drawing distances

To make the difference in movement obvious, trace each path with a pencil or marker. Have someone hold the see-saw steady on chart paper, while you trace the movement first of the cat, and then of the mouse, as in the figures above. Ask students:

  • What difference do you see between how the cat moves and how the mouse moves?
  • What makes one go further than another?
  • Who further – the cat or the mouse? Why? What else do you notice about them?
  • If the other one wanted the longer ride, what would you have to do?
