A great game from Transum to practice angle estimation.

Hopefully you already know how to change a fraction to a decimal.

For instance ²⁄³ =2 ÷ 3= 0.6666… This is a recurring decimal. But changing a recurring decimal back to a fraction is a little more complicated.

UK maths teacher have produced a great video on this.

If you prefer a written explanation Study maths have produced a good introduction of how to convert a recurring decimal to a fraction.

There is also an interactive worksheet to make sure you can do it.

This site has a brilliant range of exam type questions arranged by topic to help you make sure you have got to grips with all the topics. They are for both Foundation and Higher. The only problem is that if you want the answers you have to pay for them!

Here is the site. http://bland.in/edexcel.html

Simultaneous equations are when you have 2 or more equations with two or more unknowns. You can solve them using algebra or by drawing a graph of the two equations and seeing where they cross.

This video shows you how to solve simultaneous equations using algebra.

This video shows how to solve simultaneous equations using a graph.

Some students find it incredibly difficult to visualise nets being folded up into 3 dimensional shapes. The best way to gain confidence with this is having fun making lots of different shapes and I have already blogged about an excellent site for this where you can print off all sorts of nets and make some amazing shapes. With exams rapidly approaching you may not have time for that so here is a page from Nrich where you can watch 24 different nets being folded up to make 3d shapes. Before you press play each time try to work out what the shape will look like when it is folded, then see if you were right.

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.

This game helps you practice giving the right change. My first job was in Boots the Chemist- learn this skill and maybe you could get a job in a shop.

Maths 4 us have produced a new free on-line course about Numbers in our Food.
