Foundation- Number 18 – 20/6/19

We have been investigating the number 18. We had a go at making arrays for 18. We know that an array is a pattern of objects arranged into a rectangle or square.

We found out that 18 is made of six threes.
Then someone found another way! Three sixes are 18.
Two nines are also 18!

Can you find any other arrays for 18? Can you make an array for another number? Can you explain what an array is?
