The red cross
It tells a child the answer was wrong. It never says which belief made it wrong.
THINKPRINT · FOR ACADEMIC HEADS
Eleven red crosses on the same question. Nobody asked what those children believed.
Send us one test you’ve already marked. In 48 hours you’ll see every wrong answer traced to the belief behind it — the concept, the thinking level, the trap and its likely cause.
In 48 hours: your class’s three most common traps.

WHAT THE NUMBERS SAY
The traps are everywhere. From the front of the room, they’re hard to see.

SOUND FAMILIAR?
The same trap turns up every year, in new handwriting.
A wrong answer earns a red cross and loses a mark. Nobody writes down the belief that caused it, so the method gets re-explained while the wrong idea stays put — and returns, louder, in the board year.
The method, explained again
Teachers re-teach the steps. The steps were fine; the idea underneath them wasn’t.
The topper’s one blind spot
Even your strongest students carry one trap that quietly costs marks in every paper.
HOW IT WORKS
Every wrong answer gets four labels, not one cross.
Concept, thinking level, trap and likely cause. The software drafts each label; your teacher confirms it.
1Read
Phone photos of scripts, typed marks or a 10-minute check — any test you already give.
2Label
Each wrong answer gets its concept, thinking level, trap and likely cause, drafted for a teacher to confirm.
3See the pattern
Class and child ThinkPrints show which traps cluster, and in which sections.
4Break the trap
Each top trap comes with a counter-example lesson your teacher approves.

THREE WAYS TO START
Start with one test. Grow when it earns it.
Every way ends in the same place: your school’s own list of traps, in your teachers’ words. Choose how much help you want.

WHAT YOU’LL SEE FIRST
You’ll feel it when eleven children turn out to share one belief — and a single counter-example breaks it.
MAKE IT YOURS
Your traps, named in your staff room’s words.
ONLY AT YOUR SCHOOL
Your school’s own trap library
Your HoDs name each trap the way your staff already talk about it — “the shrinking denominator”, “the one-case proof”. Every ThinkPrint and lesson then uses your names. Teachers approve each one, and the library never leaves your school.
- Named by HoDs, approved by teachers
- Never shown to children as a label
- Mapped to your board’s concepts underneath

WHY IT GETS BETTER EVERY TERM
Every test teaches your trap library something new.
Each label a teacher confirms sharpens the next one. Within a term, your school holds a map of its own recurring traps — and of the counter-examples that broke them.
Your teachers’ corrections train it, so the labels fit your classrooms better with every paper.

WHERE IT LEADS
Once you can name a trap, you notice where it lingers.
When your own ThinkPrints point somewhere new, we show you the maths first. Whether it’s worth it is your call.
WHEN YOU NOTICE
The same trap catches a quarter of a class on two tests running.
Zero Gap LoopTHE MATHS · AN EXAMPLE
e.g. 8 classes × 3 lasting traps × 3 re-teach periods = 72 periods back a term
WHEN YOU NOTICE
Class 10–12 traps cluster on timed or negative-marked questions.
PupilPrepTHE MATHS · AN EXAMPLE
e.g. 120 aspirants × 6 mock reviews × 20 minutes = 240 mentor hours a year
WHEN YOU NOTICE
Three or more teachers are re-teaching the same trap in different sections.

e.g. 20 teachers × 1.5 hours a week × 30 weeks = 900 hours back a year
A WORKING SCHOOL · BALLARI · SINCE 2001
We correct scripts too. Here’s what we promise.
PupilTree is a working school group in Ballari, teaching since 2001 — so we built ThinkPrint for staff rooms like ours. Founding schools shape the trap library with us, keep founding terms, and can step away easily.
