For homeschool parents and classroom teachers
Photograph the finished worksheets. Get draft scores back. Confirm the ones it couldn't prove.
Kids keep working in pencil. You take a picture of each page. Class Margin reads the work, checks the arithmetic itself, and puts the photo next to every score. You only look at the answers it could not prove. Nothing is final until you say so.
The stack stops owning the evening. That is the margin — time in the classroom, or at the table, for the work that is not grading.

These three numbers are not typed into this page. Every time you load it, the same grader that runs on a real paper runs on the sample above.
answers on the sample worksheet, recomputed and proved.
answer arithmetic cannot check. Class Margin says which one.
scores a model is allowed to finalize. Every one is a draft until a person says otherwise.
Proved means the math was done again from scratch and agreed. Read means the answer is clear but is not something arithmetic can check. Check means it needs you.
Three things you do. The rest runs while you shoot.
You photograph. You confirm what it could not prove. You mark the paper final. That is the whole job that needs a person.
Photograph the stack
Any order. No names and no assignment to pick first.
Confirm the flagged answers
Arithmetic already proved the rest.
Mark it final and export
A CSV your records or gradebook can read. Only a person can finalize a score.
Twenty papers is twenty photographs
Reading runs behind you. Nothing to pick and no waiting between shots — each paper is sent on its own, so a dropped connection costs that paper and not the stack.
Every score sits next to the photograph it came from
Marks run in question order across the top. One glance tells you whether one answer needs you, or ten do.
Same tool. Two kinds of stack.
The signup is the same either way — a name, an email, a password. Only the next question differs, and you can change your mind afterwards.
A class set, a camera, a free period back
Rosters can carry class numbers and school IDs, so a paper labeled “3” still finds the student. Classes live inside a school year, and scores export as a CSV the gradebook already understands.
An assistant can photograph and match a class's work. They cannot confirm a key or finalize a score.
Start the account here; a quote comes before any billing, and there is no school checkout. What a school pays.
Start with your classYour children, your table, the evening back
Add first and last names and start: no staff, no invitations, no school year to open.
Work stays two years, which is what a portfolio needs, and a CSV covers an evaluation or a records request whenever one turns up.
Start with your own childrenWhat this is for
What it is: one adult photographs finished paper, confirms the draft scores, and keeps the photograph beside every one. If you came looking for something else, better said here than discovered later.
Not a homework helper
It does not solve the page. It grades work that is already done.
Not an app for the child
There is no student login. An adult photographs finished paper; that is the whole of it.
Not a curriculum or planner
It does not write your curriculum, generate worksheets or plan your week. One job: grade the stack in front of you.
Not a district platform
Nothing to integrate and no rollout. Built for a class, a co-op or a kitchen table. A school that needs a signed agreement asks for a quote; a household starts itself.
Paper first
The children keep the pencil. You keep the margin.
No login for your child, no tablet, no typing answers into a box. They finish the page the way they always have.
Everything Class Margin does happens after the pencil goes down. An adult is the only person who signs in.
Start here
Get the stack off the table. Keep the margin.
Photograph a real pile this week. Confirm what it could not prove. Put the scores in the book. The hour that used to belong to the papers belongs to the class, or the table, again.
