Exactly.
Anyway.
My child is in year 4.
I'm practicing questions with her.
With Maths they always teach you something basic but then you have to learn to apply that knowledge.
So learning multiplication. 6x7. And cm/ metres
But then learning how to apply the knowledge.
So doing questions such as.
A half a metre length of cloth is cut up into 6cm pieces. How many cm are left.
If you can apply the knowledge that you learn then you should be able to work out more complicated functional maths.
E.g. the standing rate for electricity is 30p a day.
Each of Kw energy cost 5p.
How much would you expect your electricity costs to be after 5 days if no energy is used.
If you use 250kw energy a day. How much would electricity cost for 7 days. ( dont forget standing charge.)
If you have you put £10 on your prepayment meter which is already £4 in debt. After how many days can you expect to need to top your meter if you use 110kw of electricity a day.
Etc
The actual maths used isnt complicated, but the comprehension on what the question is asking and being able to apply that knowledge to everyday situation is what's important.
The actual maths needed is all learned in primary school.
