Do one lesson a day for 30 days. If you don't see visible progress in your child's maths, email me and I'll refund you in full.
I can offer this because I know what happens when a child finally gets taught the methods properly, in the right order. You take no risk at all.


"So encouraging to see her study semi-independently, regardless if she improves at Maths."
- Rosie, mum of an 8 year old
"When kids get to do easier work, then the anxiety dies down. I let him do 2 easy pages and then he was more willing to do grade level stuff so we feel like we are not behind."
- Yianjoo, mum of a 9 year old
"I wanted a clear plan of action, I wanted reassurance that we could get him on track."
- Mira, mum of an 8 year old
Primary maths is really two different things wearing one name.
Reasoning and problem solving: Word problems, multi-step questions, "explain your answer". This is where school spends most of its time.
Arithmetic: The written methods. Where the numbers go, where the line goes, which end you start from. There are exactly 15 of them.
Here's the part nobody tells parents. Reasoning is built on top of arithmetic. Always. A child can't reason their way through a problem if they can't do the calculation the problem asks for.
So when your child gets a word problem wrong, it looks like a reasoning problem. It almost never is. The method underneath was never secure.
And the gap is usually further back than it looks. A child drawing dots and circles to work out 165 divided by 5 doesn't have a division problem. It's place value, several methods earlier. Practise division for a month and nothing changes.
That's why apps and extra worksheets haven't worked. They test your child over and over. But testing isn't teaching. If a method was never taught properly, being tested on it a hundred more times won't give it to them.
Arithmetic Mastery 2.0 finds the gap, teaches the method, then practises it, in the right order, until your child owns all 15.
Stop trying to fix the word problems. Fix the arithmetic underneath them.
I'm not good at maths myself. Can I still do this?
Yes. I teach every method on video and your child copies from me. You don't need to know anything, and it actually helps if you don't teach your own version, because school methods have changed since we learned.
How long does it take?
About 10 minutes a day.
Will it match what they do at school?
Yes. These are the standard written methods, aligned to the National Curriculum for England and Wales and the Scottish Curriculum for Excellence.
My child is 11 and quite far behind. Is it too late?
No. Older children move through the early modules quickly, and that confidence carries them into the ones they missed. The starting assessment shows you where to begin.
Is it a subscription?
No. One payment of £49 and it's yours for life.
They're missing a small, specific set of methods. There are only 15, and every one of them can be taught.
Nobody has sat down and taught all 15 in order, because there's never time in a class of 30. At your kitchen table there is time. Ten minutes of it.
£49. One payment. Lifetime access.
