The news today is concentrating on UK students performance in maths, and how the students in countries like China, Korea and Japan seem to be doing much better.
Why not have a go at some of the test questions and see how you can do?

This is what the Guardian has to say about it. The OECD believe their results show that boys are better at maths than girls. Do you think this is true? Over the many years I have taught maths I have not found a great difference between the sexes, but I do acknowledge that the boys generally find shape and space activities such as working with nets of three dimensional shapes easier.

Find as many different calculators as you can. Your phone,
your computer, the one in the back of the overflowing drawer in the hall. Then try this sum on all of them.
4+ 7 x 3
Do all the calculators give the same answer? What is the correct answer?
If you have a cheap four function calculator you will have got the answer 33, because it always calculates in the order you enter the sum. Unfortunately this is not mathematically correct!
If you used a scientific calculator you will have got the answer 25 which is correct. Scientific calculators understand the correct order to do calculations. Multiplication is more important than addition, so this comes first.
So how do we know what order to do calculations in? We use a rule called BIDMAS.
B rackets
I ndices
D ivision ÷
M ultiplication x
A ddition +
S ubtraction –
Always do brackets first. Then do any indices (like 2 squared or square root of 16). Some people refer to BODMAS where the O stands for “of”.) Division and multiplication come next (these have equal priority). Last is additions and subtractions (also equal priority)

In these days of austerity, benefits are being cut and prices continue to rise. It has never been more important to be careful with your money, as getting into debt can spiral out of control and have dire consequences. A first step in taking control of your finances is to understand what you spend your money on. This sheet will help you work this out. To do it accurately you will need to record your spending carefully for several weeks but you may be able to estimate figures until you have got more accurate information.
Fill the figures in for an average month. So for example if you pay an MOT fee of £54.85 each year this would be recorded as 54.85/12 = £4.57 a month. If you spend £10 at the pub once a week that would be recorded as 4 x £10 = £40.
There is also an on-line version which does the sums for you here.
