A grading tool for math teachers
Built for handwritten math.
Markscanner helps teachers scan, review, and grade handwritten math quizzes and tests faster. It suggests marks, partial marks, and per-question feedback, flags uncertain answers for your review, and helps generate a clean one-page feedback sheet for each student — while you stay in control of the final grade.

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 solutions. Whether you upload a test you already give or create a new one, it drafts the rubric (what each question is worth and how marks are assigned) for you to review and approve.
Then upload a scanned PDF or images of student work. Markscanner grades against the rubric you approved, and you review the draft marks and comments question by question before approving final results and printing 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.
Where it fits
Three kinds of quizzes Markscanner handles well
Start-of-unit
Diagnostic quizzes
Find out what students remember from last year before you start teaching. Use the results to plan where to start.
Weekly
Formative quizzes
Catch misunderstandings fast. Reteach what's not landing while the content is still fresh.
End-of-unit
Summative tests
Grade an entire class set in the time it used to take to grade five.
How it works
From a fresh test to graded feedback, in five stages
-
01 · Upload or create
Upload the tests you already give, or create a new one with Markscanner. It drafts a marking rubric from your materials for you to review and approve before grading.
-
02 · Print
Print it on regular paper. No QR codes, no custom booklets. Hand it to your students.
-
03 · Scan
Scan or photograph the finished class set in one upload. Markscanner figures out which page belongs to which student.
-
04 · Grade
Draft marks and per-question comments appear. You review every answer, adjust where you disagree, and approve.
-
05 · Report
Print per-student feedback sheets, export a class CSV, and see which questions tripped the class up.

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.
-
A/B versions to discourage copying
Run Version A and Version B of the same test. Markscanner tracks which paper each student wrote and grades accordingly.
-
Generate blank tests with AI
Draft a new quiz or chapter test as a printable vector PDF, with an optional Version B variant.
-
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.
Blank test generation
Draft your next quiz with AI
When you need a fresh test, Markscanner can also generate one for you. Pick a topic, difficulty, and number of questions; Markscanner drafts the quiz as a printable vector PDF with proper math typesetting. You edit what you want, regenerate individual questions, and print. An optional Version B variant is produced from the same source to discourage copying.
- Vector PDFs with selectable, searchable math.
- Per-question regenerate when one isn’t quite right.
- Canadian spelling, metric units, and Canadian contexts.
- Answer-key PDF generated alongside the student copy.
Chapter 6 quiz
Version A
1. Solve for x: 3x + 7 = 22 [2 marks]
2. Factor the expression x² − 5x + 6. [3 marks]
3. Graph y = (x − 2)² − 4 and label the vertex. [4 marks]
