A free ten-minute check of where your child is stuck
It traces back from the questions they get wrong to the skill that's actually missing.
Practice then starts there: a few minutes a day, most days. There's no streak to keep up: a new week starts empty.
We ask you to sign in so we can keep your child's results and use them to pick what they practise next.
Sign in with an email address or a Google account. Then set up your child's dino and let them play. The check takes about ten minutes, and we take no card for it.
At the end you see something like: “Getting stuck on adding across 10. We've traced it back to number bonds to 10 and we're teaching that now.” If nothing is missing, it says that instead.
Try three questions yourself
You answer three questions and see how the tracing works. No sign-in, no child profile, and nothing is saved. It is a demonstration run, so it tells you nothing about your child.
The button for it is on the app's first screen.
Why Numbersaurus exists
Numbersaurus started with my daughter. She was falling behind at maths at school, and had started to be talked about as someone who was simply bad at it — “I guess she's more of a creative”. Practising at the level her class had reached ended in frustration every time.
We thought about a private tutor. Instead I spent time working out where the problem actually was, and found that some fundamentals had never become solid. A sum that combined two or three steps took so much working out that she would lose the thread, get frustrated and want to do something else.
I built the first version of Numbersaurus so she could practise the missing fundamentals, and it worked. She practises most days now; the regular habit is the part that made the difference. She says she is good at maths and wants to do it.
The same thing happened to me. I was hopeless at maths at primary school, and barely reading; it was a dreadful school. My mum, a teacher, home-schooled me for a term (for reasons that had little to do with school), and found that, taught properly, I was good at maths. Tested at the start of secondary school, I went straight into the top set, and later on to degree-level maths.
My daughter needed work at the level that was actually missing, not the level her class had reached. What fixed my own was teaching done properly, going back over what I had missed. That is what I have tried to build: practice at the level your child needs, in a game they want to come back to. It is working for my daughter, and I think it can work for your child too.
Questions parents ask
How does it fit with what school teaches?
Numbersaurus follows the number strand of the UK curriculum, Reception–Year 6: counting, place value, addition, subtraction, multiplication and division. Fractions are covered to Year 3. Decimals, percentages and ratio are not covered yet. The skills we do cover are mapped with what each one builds on, so when a child is stuck the practice goes to the skill underneath: the tracing a teacher would do for every child if a class of thirty left time for it. What we teach lists every skill, and what isn't covered yet.
Is it instead of a tutor?
No. A tutor is a good option, and the two work together: a tutor can start from what the check finds. Numbersaurus is £5 a month for the whole family.
My child already uses a times-tables app. Is this the same?
No. The difference is who chooses. Numbersaurus picks the next skill rather than letting a child choose the one they already like: practice stays just past what they have secure, and moves on as they secure more.
How much time does it take?
A few minutes a day, most days. There's no streak to keep up: a new week starts empty.
What does it cost, and what's free?
The check is free, and so is the first week of practice for the whole family. Your child plays after you sign in, with an email address or a Google account: signing in first means their answers go into your family record from the first question, instead of sitting on that one device. We take no card, so nothing charges automatically. You can answer three questions yourself without signing in, to see how it works. When the week ends, a child can still play four rounds each visit for free. Keeping going is £5 a month or £50 a year.
