Instructions
There are two variations of questions:
Variation 1: Work out how many free-standing blocks are required to make this 3D shape.
Variation 2: Select how the following 3D object would appear in a top-down, plan view (looking from above).
Method
Variation 1: Count all blocks, including those that you cannot see but would be needed to support the blocks you can see.
Tip: It could be helpful to count each layer of blocks separately and then add them together.
Variation 2: Look at the grey tops of the blocks as they will help you workout what the top view could look like.

Variation 1
Work out how many free-standing blocks are required to make this 3D shape.
Example Question 1:
Answer: 11 blocks
Explanation: Bottom layer: 6 blocks, middle layer: 4 blocks, top layer: 1 block. Total = 11 blocks
Variation 2
In this type of question you need to work out how a 3D object would appear in a top-down, plan view (looking from above).
Example Question 2:
Answer: b
Explanation: Look at the shaded side of the blocks on the left, they will help you work out the correct answer.
