  • Question 1

What do we call the group of shapes that are 'flat'?

CORRECT ANSWER
2D
EDDIE SAYS
How did you do? 2D means that a shape has been drawn on the paper. It would be impossible to pick up!
  • Question 2

Name the following shape:

 

A 3-d with six faces, which are not all the same.

CORRECT ANSWER
Cuboid
EDDIE SAYS
The clue with this question was the word 3D. In simple terms, 3D means that you can pick the object up. The second clue is that the sides are not all the same, so it cannot be a cube.
  • Question 3

​3-d with six identical faces must be a cube.

CORRECT ANSWER
True
EDDIE SAYS
Did you pay attention to the last question? This statement has to be true. The only 3D shape with identical sides and faces is a cube
  • Question 4

What is the name for a 2-d shape with five sides?

CORRECT ANSWER
Pentagon, Hexagon, Square
EDDIE SAYS
This comes down to knowing your 2d shapes. Remember, if you are struggling you can always click back to the introduction to help you are you go.
  • Question 5

Name the following shape:

 

3-d and round

CORRECT ANSWER
Sphere
EDDIE SAYS
Did you get this right? You need to know the difference between 2D and 3D shapes. There are similarities between the circle and the sphere. Think about whether you can pick the shape up.
  • Question 6

The following shape is a circle

 

 

CORRECT ANSWER
False
EDDIE SAYS
This was a bit of a tricky question, did you think about it carefully? The image is of a ball, and you can pick this up, so this must be a 3D shape. A circle is not a 3D shape, it is a 2D so the statement must be false.
  • Question 7

What is the collective name for 

A 2-d shape with at least 3 straight sides and angles (typically 5 or more)

CORRECT ANSWER
Polygon
EDDIE SAYS
The key to this answer is the word 'collective'. Any shape that has 3 or more straight sides and angles can be called a polygon.
  • Question 8

Name the following shape:

A 2-d shape with 8 corners

CORRECT ANSWER
Octagon
EDDIE SAYS
A 2-d shape with 8 corners - octagon
  • Question 9

Name the following shape:

 

A 3-d shape with 8 corners

CORRECT ANSWER
Cuboid
EDDIE SAYS
A 3-d shape with 8 corners - cuboid
  • Question 10

Name the following shape:

 

A 2-d shape which is half a circle

CORRECT ANSWER
Semicircle
EDDIE SAYS
A 2-d shape which is half a circle - semicircle
