Rotations

Rotations. Rotations are when one object moves to another place. It’s almost like when you rotate to different classes during the day. Shapes can be rotated! They rotate 90 ⁰, 180 ⁰, 270 ⁰ and 360 ⁰. These are also known as one quarter turn, half turn, three quarter turn and a full turn.

1. Rotations

2. Rotations are when one object moves to another place. It’s almost like when you rotate to different classes during the day.

3. Shapes can be rotated!They rotate 90⁰, 180⁰, 270⁰ and 360⁰. These are also known as one quarter turn, half turn, three quarter turn and a full turn.

4. Before we rotate, let’s review clockwise and counterclockwise.

5. Clockwise

6. Counterclockwise

7. Let’s check out some websites that show rotations.

9. Now it’s your turn! Get your polygon (shape). Find your start point. Let’s rotate!

10. Find your start point. Rotate 180⁰( half turn) clockwise.

11. Find your start point. Rotate 270 or 360⁰ (three quarter turn or full turn)clockwise.

12. Now rotate counterclockwise (backwards) after you find your start point.First, 90⁰ counterclockwise.

13. Now rotate 180⁰ counterclockwise (half turn).

14. And rotate one full turn counterclockwise (360⁰).

15. Awesome! Now let’s do some more practice!

16. Now, rotate the top shape 90⁰ clockwise.Rotate the bottom shape 90⁰ counterclockwise.

17. OK, now rotate your top shape 180⁰ counterclockwise and your bottom shape 90⁰ clockwise.(Make sure your start points are together.)

18. Wow! Great job!Now one more…

19. Turn your bottom shape 360⁰ clockwise and your top shape 360⁰ counterclockwise.

20. Ok, ok…one more!Turn your top shape 180⁰ clockwise. Turn your bottom shape 90⁰ clockwise.

21. You are now expert rotators!
