​Maths Matters

This week the Maths Matters students have written questions about the picture below. 

Prep

Can you count all of the dots in the picture? 

Year 1

Hudson says that this shape is 12 dots long. Lucas says that this shape is 24 dots long. 

Look at the picture and see if you can explain why they got different answers. 

Year 2

24x12=                                12x24=                                2x144=

4x72=                                   144x144=                           288x1=

72+216=                             1+287=                                286+2=

Year 3

Try to spot 10 different arrays in the picture. They can be from any times table. 

Every World Cup has 48 countries. If each dot represents one country, how many World Cups can be represented by this picture?

Year 4

How may 3x3 arrays can you find in the picture?

Year 5

If each dot is 1cm and the space between each dot is 1cm, how long is each side? 

Can you work out the area of the shape too?

Year 6

If one quarter of the object has an area of 216cm squared, what is the total perimeter of the object? 

If one dot is 1cm in length, what is the perimeter?
