Compass Game

The compass below shows the four directions of North, East, South, and West. The red arrow points in one of those directions. See the black turtle in the middle of the yellow circle? How much of a turn does he have to make to point to the red arrow? He can only turn clockwise by 0/4, 1/4, 2/4, 3/4 or 4/4 of a circle. Press a button or a fraction circle to make him turn. If the turtle turns to face the arrow, you score points. If not, the red arrow will blink. You can press the "show me how" button to see how it's done, but you can only score points by pressing the right fraction button or fraction circle.
