• A way of putting mental maths at the heart of maths teaching and learning.
• Competitive and enjoyable way of promoting children’s understanding of their mathematical learning.
• Children progress through basic number skills which are linked to particular continents.
• Once one continent is completed, the child’s progress is celebrated and they travel to the next continent to work on targets with greater challenge.
• Children are competing against themselves and their learning and understanding, not against other children.
• The challenge for each child is to constantly improve and become faster at mental maths.
In reading, the whole point of being able to do the basics – read the words
- is to understand what you have read. You can’t say you can read unless you understand the words you have read as a whole text.
In maths, the important part is to be able to use the basic skills – number bonds, multiplication tables, halving, doubling -- in problem solving and real life applications. If you want to know what is the best value in the supermarket, you need to be able to work out the price per 100g of a product when it comes in different sizes.
Or you want to buy 4 plane tickets at £160 each. Do we really want our children to have to get out a calculator or use paper and pencil for a simple calculation?
How would you work this out?
Method 1 Use times tables
4 x 100 = 400 4 x 6 = 24 so 4 x 60 is 240
400 + 240 = £640.
Method 2 Use doubling
Double 16 is 32, double 32 is 64.
So double 160 is 320, double 320 is £640.
It doesn’t matter which way you work it out, as long as you know what to do and can work it out quickly.
SATs for Year 2 seem to be here to stay. The new revised
National Curriculum has raised the standards to a certain extent. If a child can do all the skills on Africa, they will find it easier to get a good level 2.
If they can do all the skills on Australasia, they will find it easier to achieve level 3.
SATs include other aspects of maths; shape and space, measure, data handling and problem solving. But knowing these key skills instantly will give your child a head start in being able to apply them.
Year 6 SATs also seem to be here to stay.
• 2 written papers – new for 2014, neither paper will allow the use of a calculator. Emphasis is on written and mental methods. Children will need to be able to do quite complex calculations with several steps under timed conditions.
• mental maths paper – need almost instant recall of basic maths skills. 5 seconds, 10 seconds and
15 second questions.
Testing in school. How would you do?
Copy down the numbers on the screen onto your grid.
We are going to do the 7 times table. You have 30 seconds.
Where it says eg 3, you write the answer to 3 x 7.
Don’t write the calculation.
If you finish all 10 within 30 seconds, write down how many seconds you have left.
Passports are based on the continents of the world.
There are currently 7 – we may add another for those that finish all 7.

Remember
First stage is to learn what each skill needs. Tables can be learned by rote or sung to start with.
Then build up speed. The aim is to get faster. When you think your child is ready to be tested on a part of the passport then initial that section and send the passport into school for the class teacher to see.
When tested in school:
Answers need to be instant. They all need to be correct.
No fingers, no counting or chanting through the tables.
Practise little and often.
