Hi,

They are what I would cal 'pre-algebra' questions ie some people will want to kae equations but they can be solved logically.

FYI -the first one:

**Quote:**

A school choir has 72 members altogther. The number of girls is 6 more than the number of boys. How many girls are there in the school choir?

If the numbers were equal there would be 72/2 = 36 of each.

So if we want the difference to be six we add 3 to get 39 - if children play with number they will see why this works. This could be a level 4 question in the KS2 tests.

The second is harder because the concept of age always seems to make children struggle because they forget that both people age!

**Quote:**

Max is 8 years old. His father is 34 years old. In how many years' time will his father's age be three times of Max's age?

I might start this sort by setting out two columns:

Max ..........Dad

8 .......... 34 ...... now

9 .......... 35

10 ......... 36

11 ......... 37

12 .......... 38

13 .......... 39

We can check at each stage whether it works or not - this is a trial and improvement method ... I'd expect brighter level 5s to get it if set out logically.
