The problem
Why grading math is hard
Math isn’t just right or wrong. Two students can reach the same answer through completely different work, and another can have the right method with a single arithmetic slip. The steps carry most of the learning, and most of the marking.
-
Partial marks take time
Deciding partial credit takes longer than checking a final answer.
-
Many valid forms
Factored, expanded, mixed number, decimal — all deserve credit.
-
Steps matter
The worked steps carry the learning, not just the last line.
-
Handwriting is messy
Some pages are ambiguous on purpose. A model shouldn’t just guess.
-
Feedback is most useful fresh
The sooner students see their work marked, the more the comments actually land.
Grading a class set of handwritten math shouldn’t mean losing your evenings and weekends. It also shouldn’t mean handing the job to a machine that doesn’t understand how math work actually looks on paper.
What it is
A review-and-approve marking assistant
Markscanner is a web-based marking assistant for teachers who still work with printed quizzes, chapter tests, and handwritten student solutions. Upload a scanned PDF or images of student work, review draft grading and comments question by question, then approve final results and print a one-page feedback sheet for each student.
It’s a review-and-approve workflow, not blind automation. You stay the teacher; Markscanner does the repetitive first pass.
How it works
From stack of paper to feedback sheet, in seven steps
- 01
Upload a scanned PDF or images
Drop in the full class set. No special paper, no QR codes required.
- 02
Pages, questions, and students get organised
Markscanner groups the pages that belong to each student and matches them against your class roster.
- 03
Draft marks and per-question comments
Each answer is compared against your rubric or answer key, with partial credit on sub-questions.
- 04
Uncertain answers get flagged
Messy handwriting, unusual approaches, and low-confidence results are called out for your attention first.
- 05
You review, adjust, and approve
Change a mark, rewrite a comment, or regrade a single submission. Nothing is final until you say so.
- 06
Print a one-page feedback sheet for each student
Grades, per-question comments, strengths, and next steps — ready to staple to the returned paper.
- 07
Export grades to your gradebook
Download a CSV of the class results to drop into whatever gradebook you already use.

Benefits
What teachers get out of it
-
Spend less time on repetitive marking
Focus on the flagged and ambiguous answers, not every single one.
-
Return feedback sooner
Get tests back while the content is still fresh for students.
-
More consistent per-question comments
The same mistake gets the same note across the whole class set.
-
Printable one-page student feedback
Grades, comments, and next steps on a single sheet per student.
-
Spot class-wide error trends
See where the class struggled so you know what to reteach tomorrow.
-
Teacher oversight on every final grade
Nothing goes to a student until you’ve approved it.
Teacher-in-the-loop
Markscanner is designed as a teacher-in-the-loop system. It helps with draft marks, comments, and organisation — but you stay in control of final grades.
Low-confidence and messy responses are flagged for your review before anything is finalised, and every mark is editable before the feedback sheet is generated. The goal isn’t to hand marking over to a model — it’s to take the repetitive first pass off your plate so your time goes to the judgment calls only a teacher can make.
Per-student output
A one-page feedback sheet per student
After you approve, Markscanner can generate a clean one-page printable feedback sheet for each student: their grade, per-question comments, what they did well, and what to work on next. It’s the kind of feedback most teachers want to give every student but rarely have time to write by hand for thirty papers in a row.
- Grade, per-question comments, strengths, next steps.
- Editable before print — rewrite a comment in your voice.
- Print & staple to the returned paper.

Class insights
Know what to reteach tomorrow
Because every question gets marked the same way, the class data actually means something. See which questions tripped up the most students, spot common mistakes across submissions, and know exactly what to reteach tomorrow — without paging back through thirty papers to piece it together.
