Hi there, 3D shape detective!
Did you know that when you turn a 3D shape, you are rotating it?
Remember that you can rotate a shape either clockwise or anti-clockwise:
Take a look at these 3D shapes:
a) b) c)
They are all the same shape (cylinders) but have different sizes (widths and lengths).
Now look at these same shapes once they have been rotated:
1) 2) 3)
Can you match each cylinder to its rotation?
Cylinder a matches with rotation 3.
Cylinder b matches with rotation 2.
Cylinder c matches with rotation 1.
We can use the lengths and widths to help us pair each cylinder with its rotation.
In this activity, you will need to be a 3D shape spotter and match the shapes to their rotations.
Pssstt!! Here’s a handy hint to help you reach superstar status:
Before you begin matching, look closely at the features of the original shapes (e.g. number of sides, 2D shapes they are made from, length and how wide they are).
Once you have identified these key features, it will be much easier to spot the correct rotation.
Let’s get started!
