2. Which Way? Start facing the Promethean board or “north”. Turn left. Turn right. Do a U turn. Which way is the car heading?

3. Which Way? Start facing the Promethean board or “north”. Do a U turn. Turn right. Turn left. Turn left. Which way is the car heading?

4. Which Way? Start facing the Promethean board or “north”. Turn right. Turn right. Turn left. Turn left. Which way is the car heading?

5. Which Way? Start facing the Promethean board or “north”. Turn left. Turn left. Turn left. Do a U turn. Which way is the car heading?

6. What Degree? We can assign our turns a measurement in degrees. Go to ActiveInspire and use the modified protractor to illustrate this.

7. Which Way? Start facing the Promethean board or “north”. Turn 180 degrees. Turn 90 degrees right. Turn 180 degrees. Which way is the car heading?

8. Which Way? Start facing the Promethean board or “north”. Turn 270 degrees left. Turn 90 degrees right. Turn 180 degrees. Which way is the car heading?

9. Which Way? Start facing the Promethean board or “north”. Turn 270 degrees right. Turn 90 degrees right. Turn 180 degrees. Which way is the car heading?

10. Which Way? Start facing the Promethean board or “north”. Turn 90 degrees right. Turn 90 degrees right. Turn 270 degrees left. Which way is the car heading?

11. Which Way? Start facing the Promethean board or “north”. Turn 90 degrees east. Turn 90 degrees east. Turn 270 degrees east. Which way is the car heading?

12. Which Way? Start facing the Promethean board or “north”. Turn 180 degrees. Turn 90 degrees east. Turn 180 degrees. Which way is the car heading?

13. Not only can we assign degree measurements to describe our turns, we can also assign fractions to those turns. First off, let’s divide our protractor into fourths. ¼ ¼ ½ ½ ¼ ¼

14. So, if my car is facing to the right and I make a ¼ turn to the left, which way will my car end up facing? ¼ ¼ ¼ ¼

15. The car is facing north to start. It turns ¼ turn to the west. Then ¾ a turn to the right. Which way is it facing now? ¼ ¼ ¼ ¼

16. Which Way? Start facing “north”. Turn 180 degrees. Turn ¼ to the right. Turn 270 degrees to the left. Turn ½ way around. Turn 90 degrees to the right. Which way is the car heading now?
