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.
Before we rotate, let’s review clockwise and counterclockwise.
Clockwise
Counterclockwise
Let’s check out some websites that show rotations.

Now it’s your turn! Get your polygon (shape). Find your start point. Let’s rotate!
Find your start point. Rotate 90 ⁰ (quarter turn) clockwise.
Find your start point. Rotate 180 ⁰ ( half turn) clockwise.
Find your start point. Rotate 270 or 360 ⁰ (three quarter turn or full turn) clockwise.
Now rotate counterclockwise (backwards) after you find your start point. First, 90 ⁰ counterclockwise.
Now rotate 180 ⁰ counterclockwise (half turn).
And rotate one full turn counterclockwise (360 ⁰).
Awesome! Now let’s do some more practice!
Now let’s see what happens when you have two objects to rotate !
Take your two shapes and place their endpoints in the same direction.
Now, rotate the top shape 90 ⁰ clockwise. Rotate the bottom shape 90 ⁰ counterclockwise.
OK, now rotate your top shape 180 ⁰ counterclockwise and your bottom shape 90 ⁰ clockwise. (Make sure your start points are together.)
Turn your bottom shape 360 ⁰ clockwise and your top shape 360 ⁰ counterclockwise.
Ok, ok…one more! Turn your top shape 180 ⁰ clockwise. Turn your bottom shape 90 ⁰ clockwise.
You are now expert rotators!
