Abacus Trainer: mental maths, mastered
Abacus Trainer drills mental arithmetic and grades a student’s answer whether they say it aloud or photograph their handwritten working — read with OCR. Built-in screen-time caps keep practice healthy for the young learners who use it most.
Who it’s for: For primary students building mental-maths speed and their parents.
How it works
Take a drill
The trainer presents mental-maths problems at the right level for the student.
Answer your way
The student speaks the answer or photographs their working; speech recognition or OCR reads it.
Practice in healthy doses
Screen-time caps stop sessions running too long, keeping practice sustainable for young children.
See it in a real classroom
Dictation runs in Hindi at competition speed; Ravi answers aloud — "The answer is 42" — and speech recognition grades it instantly. For the weekly timed sheet his father prints the PDF; Ravi solves on paper against the countdown, photographs the grid, and OCR auto-grades it with a bead-replay of the one he missed. At 25 minutes, the screen-time cap ends the session.
Why it matters: Real abacus training — spoken, on paper, and time-capped by design.
Who uses it, and for what
Students: Placement, lessons, tables, timed sheets and exams — 13 doors, one track.
Teachers: Class board, assignments and weekly coach reports.
Principals: Programme-level oversight on the class board.
What makes it different
Spoken-answer grading
A student can simply say the answer, which suits fast mental-maths drills and early readers.
Handwriting OCR
A photo of handwritten working is read and graded, so paper practice still counts.
Screen-time caps
Daily limits keep young learners’ practice healthy and reassure parents.
Questions schools ask
Can young children use it without typing?
Yes. They can speak the answer or photograph their handwritten working — no typing required, which suits early primary.
Does it limit screen time?
Yes. A daily screen-time cap ends sessions before they run long, keeping mental-maths practice healthy for young children.
