Fran and David were playing with a circle and an oblong on the 4
x 4 board in the picture.
Now Fran has the oblong and David has the circle. Fran knows that
oblong can only move sideways (left or right) while David knows that circle can only move
from bottom to top. Both shapes move one square at a time.
Where are the shapes after 3 moves? Try other starting places, can you
land on the same square after 3 moves?
