Maths that knows why your child got it wrong.

Ten minutes a day. Every slip named and fixed the same day, a two-minute weekly card telling you what to ask, and a chart you can't argue with.

Every child picks a friend who talks them through the day.

Why it works

Four things, every day, in ten minutes.

Each one is a well-studied way children learn maths. Together, in one daily habit, they are what the apps and the worksheet centres leave out.

A short timed sheet

Placed where your child is fast and sure, often a little below their grade. Pass twice to move up a small step. Slip three times and it steps back.

Retrieval practice and mastery learning, the two best-evidenced techniques in learning science. Dunlosky et al. 2013; EEF Toolkit, about five months' extra progress a year.

Why it went wrong

Every wrong answer is matched to a known slip and named in one line: "took the smaller digit from the larger". Two more of the same follow, so it gets fixed today.

Most arithmetic errors are systematic, so they can be diagnosed and corrected. Brown and Burton 1978; Metcalfe 2017.

Think it through

A word problem on the same numbers, a worked sum with a fault to find, and an estimate before computing. Untimed, read aloud on request.

Finding the fault and estimating first build the understanding fluency alone misses. Booth et al. 2013; Siegler and Booth 2004.

Say it aloud, once a week

A two-minute card for you or the teacher: three questions to ask, what a good answer sounds like, one slip to watch for. One tap to record what you heard.

Explaining your own thinking deepens learning: 64 studies, g 0.55. Bisra et al. 2018; EEF Toolkit on parental engagement, three to four months.

Nothing hidden

We measure what we train, so you can't miss it.

The same ten minutes trains and measures. Every answer, every second, every slip goes on your dashboard the moment the sheet ends.

Our promise

Ten minutes a day for thirty days. If the chart hasn't moved, we'll show you exactly what happened and fix the plan with you.

Twelve sheets is enough to see whether speed, accuracy and level are moving, and the app tells you which one isn't.

Not like the others

Different, on purpose.

Most maths apps do one thing well and charge for it. These are the choices that make AiMA different.

Most apps
AiMA
Beside school

Not instead of it.

AiMA drills what school teaches and reports against what school expects. Ten minutes of practice a day, not a new curriculum and not a replacement for the teacher.

Mapped to the grade

Every step sits in the school year where your curriculum expects it: Canada (Ontario), Cambridge or England / Edexcel. A Year 5 child who needs level B gets level B, and you watch the distance close week by week.

Makes class time count

Homework stays homework. When facts and methods are fluent, the lesson on fractions is about fractions, not counting on fingers. The thinking track uses the applied problems school marks reward.

The teacher sees the class

Which step each child is on, which slips the class keeps making, and which thinking gaps to teach to tomorrow. No marking, and the parent sees the same record.

AiMA levels by the Ontario grade where the curriculum expects them; Cambridge Stage N and England Year N sit one column to the left. The starting check places a child by what they can do, whatever their year.

Three ways in

Made for the three people in the room.

Parents

Know where they really are.

Create a home, add your kids, and the starting check finds their real level. Your dashboard is plain and quiet: standing against the grade, today's sheet, the gaps, and the weekly card.

Create a home
Teachers

The whole class, no marking.

Create a class, add students, and see every child's level, slips and thinking gaps in one list. Parents link up with a code and see the same record you do. Free for founding schools, for good.

Set up a class
Kids

Ten minutes. Then play.

Pick a friend who talks you through the day. A path to climb, badges for sticking with it, never for logging in. Stuck? A hint, a peek at the card, or finish later.

Ten minutes that make the lesson count.

Free for founding schools, for good

Run it for a term with one class. We'll set it up with you, measure the term with you, and show you the before and after.

Class at a glance

Every child's level, slips and thinking gaps in one list. No marking.

A weekly card per child

Three questions, what a good answer sounds like, one slip to watch.

Ask AiMA about any child

"Why is Rafi stuck on subtraction?" Get a plain answer from their record.

Parents see the same record

They link with a code. One picture of the child, shared at home and school.

Fair questions

"Won't timing make them anxious?"

Sheets start where a child is fast and sure. A slip means another go, not a lower score.

"A Grade 4 child on Grade 2 work?"

Only until it's fluent. The chart shows the gap closing, week by week.

"Where does teacher time come from?"

No marking. Ten minutes a day the children run themselves, plus a two-minute card.

"Do we need a device per child?"

No. Any browser, a phone or a shared tablet. Each child signs in with a first name and PIN, and the record follows the child, not the device.

The research

Nothing here is a new idea.

What is new is all of it in one ten-minute routine, with every answer recorded against a named slip.

What does it cost?

Nothing. AiMA is free for families and for schools while we grow, and free for founding schools, for good. If anything ever changes for anyone else, every school using it will hear well in advance, and no child's record is ever lost.

Which grades does it cover?

Counting to calculus: 131 small steps from kindergarten to the end of secondary school, each placed in the school year where your curriculum expects it (Canada / Ontario, Cambridge, or England / Edexcel). The starting check places your child at the first step they are not yet fluent in, whatever their grade.

Is it a replacement for school?

No. It drills what school teaches and reports against what school expects. Think of it as the daily practice that lets the classroom time count.

Is my child just being timed on typing?

Sheets are typed on an on-screen keypad that fills like paper, and every target time carries a typing allowance. From level G up, typing credit follows the length of the answer, so no pass is decided by typing speed.

How much screen time is it?

Ten minutes a day, and the app says when the day is done. There is no feed, no video, no shop. Badges reward sticking with it, never logging in.

What do you keep about my child?

A first name, a PIN and the work. Parents are an email. Every answer stays on your dashboard, and a home can delete everything in one tap. A one-tap export is on the way.

Start with the starting check.

Ten minutes. A few short timed parts at your child's grade. Then an honest answer: this level, this far from where the grade expects, this many days to close it.

Free for families. Free for founding schools, for good. We'll measure the term with you.
