Dive into Rotations: Exploring Shapes and Movement
Delve into the concept of rotations illustrating how shapes can be moved and turned, akin to rotating through different classes in a day. Understand clockwise and counterclockwise movements alongside practical examples and engaging visuals. Discover websites demonstrating rotations, and practice hands-on by rotating polygons in various degrees.

Presentation Transcript
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 , 180 , 270 and 360 . These are also known as one quarter turn, half turn, three quarter turn and a full turn.
Before we rotate, lets review clockwise and counterclockwise.
Lets check out some websites that show rotations.

Now its your turn! Get your polygon (shape). Find your start point. Let s rotate!
Find your start point. Rotate 90 (quarter turn) clockwise.
Find your start point. Rotate 180 ( half turn) clockwise.
Find your start point. Rotate 270 or 360 (three quarter turn or full turn) clockwise.
Now rotate counterclockwise (backwards) after you find your start point. First, 90 counterclockwise.
Now rotate 180 counterclockwise (half turn).
And rotate one full turn counterclockwise (360 ).
Awesome! Now lets do some more practice!
Now lets 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 clockwise. Rotate the bottom shape 90 counterclockwise.
OK, now rotate your top shape 180 counterclockwise and your bottom shape 90 clockwise. (Make sure your start points are together.)
Wow! Great job! Now one more
Turn your bottom shape 360 clockwise and your top shape 360 counterclockwise.
Ok, okone more! Turn your top shape 180 clockwise. Turn your bottom shape 90 clockwise.
