This week, Year 3 and 4 have been investigating arrays in Maths and the Commutative Law of Multiplication. Here is our intrepid reporter, Cleo’s take on everything:
We began investigating arrays when we were given this problem.
‘In Array city the streets are numbered and every building in the street must have that number of windows to ‘fit in’.
Some owners didn’t like this so they decided to make sure their buildings looked different but still had the correct number of windows. Every row has to have the same number of windows- this is the law!’
Our investigation was to find out how many different ways we could put the windows in on the different streets.
We found out what the commutative law of multiplication was. It meant that whichever way round you multiplied the numbers it would still be the same answer.
E.g. 3×4=12 and 4×3=12
We worked really hard and even found out what a square number was! (Year 5 stuff!)
It was really fun and we learnt lots.
Why don’t ask your child’s class teacher how you can get involved in our Marvellous Maths lessons!
