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 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.
4
Before we rotate, let’s review clockwise and counterclockwise.
5
Clockwise
6
Counterclockwise
7
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!
10
Find your start point. Rotate 90 ⁰ (quarter turn) clockwise.
11
Find your start point. Rotate 180 ⁰ ( half turn) clockwise.
12
Find your start point. Rotate 270 or 360 ⁰ (three quarter turn or full turn) clockwise.
13
Now rotate counterclockwise (backwards) after you find your start point. First, 90 ⁰ counterclockwise.
14
Now rotate 180 ⁰ counterclockwise (half turn).
15
And rotate one full turn counterclockwise (360 ⁰).
16
Awesome! Now let’s do some more practice!
17
Now let’s see what happens when you have two objects to rotate !
18
Take your two shapes and place their endpoints in the same direction.
19
Now, rotate the top shape 90 ⁰ clockwise. Rotate the bottom shape 90 ⁰ counterclockwise.
21
OK, now rotate your top shape 180 ⁰ counterclockwise and your bottom shape 90 ⁰ clockwise. (Make sure your start points are together.)
24
Turn your bottom shape 360 ⁰ clockwise and your top shape 360 ⁰ counterclockwise.
26
Ok, ok…one more! Turn your top shape 180 ⁰ clockwise. Turn your bottom shape 90 ⁰ clockwise.
28
You are now expert rotators!
