MathBrush

What it costs

Nothing yet, and here is what it will cost when it does. 65 worked examples are free to anybody — two from every pattern, each with its practice questions — so you can meet all 33 without a code and without paying.

Open, in full, while it is being tested

MathBrush is being shown to a few parent groups before it opens properly, and for them every solution, every practice question and the whole worksheet builder is open. If you came from one of those posts, the code is in it. Put your code in →

No payment, no account, no card. The prices below are what it will cost afterwards, and the free examples stay free either way.

Questions people ask first

Why will it cost anything?
Every solution here is drawn, solved again independently, and checked before it is published, and new ones are made every week. The subscription is what pays for that work.
How long is the beta?
A few weeks per group, while I find out what is confusing and fix it. Nothing you use now stops working when it ends: the free examples stay free, and you will not be charged for anything without being asked first.
Can I cancel?
Any time, from the link in your receipt. A year bought is a year kept.
Is it per child?
No. One subscription, one household, however many children are using it.
How do I pay?
PayNow or a card.
What if a solution is wrong?
Tell me and I will fix it — shawn@mathbrush.sg. What gets checked before a solution is published.
