If you are new to Maths Accelerator and want to know how to use it for best results then read on.

Maths Accelerator is a simple way to practice mental arithmetic and is suitable for people between about 5 and 16 years old. You click on buttons to give your answers instead of writing by hand. You could find you can do as many questions in 10 minutes with Maths Accelerator as you do in a week of school. With that much practice you get faster!

There are lots of different types of question. You choose what to work on. With practice you will get faster, make fewer mistakes, and even begin to find the questions easy.

Like a computer game, Maths Accelerator gives you lots of information on how you are doing and where you have made progress.

Maths Accelerator does not offer all the types of maths question you do at school. It just does basic calculation. But, remember, if you can do the calculations with ease the rest is much easier to understand and to do.

Maths Accelerator is often improved and if you need a type of question it doesn't offer why not write and tell me at matthew@workinginuncertainty.co.uk.

In each session try several different question levels. Mix easy ones with tougher ones so that you stay relaxed but also challenge yourself.

On easy question levels aim to go faster, and faster, and then faster still.

Of course, if a question level matches something you have been set as homework or expect in a test soon then do lots on that level.

Fun and games are great but we all get a boost when we can see that we have done a lot and we are getting better.

Maths Accelerator uses computer game techniques to show you your progress:

As you go through a set of questions you can see which question of the set you are on and how many you have done so far in the session.

When you finish a set you can see:

how many points you have earned so far in the session, including extras;

what questions you answered in the set, how long each one took, and how many errors you made on each;

your average time per question in the set; and

the detailed information in the form of a database table that you can copy and paste into a spreadsheet for really scientific analysis.

When you click on the Session Summary button you can see:

a list of the question sets you have done so far this session with details of time taken and questions done;

your total work time so far in the session;

points earned; and

the detailed information in the form of a database table that you can copy and paste into a spreadsheet for analysis.

When you finish a set of questions you will hear the sound of a crowd clapping and cheering wildly.

On the first screen you will see a number called the random seed. Usually it is best to ignore this.

However, if you want to do a level again and get exactly the same questions as on a previous occasion, then you can do it by entering the same seed number that was visible the first time.

These random numbers are used to generate the questions afresh every time. That's why Maths Accelerator does not need a big database of questions.
