MarkScanner

For secondary math teachers who mark on paper

Built for handwritten math.

MarkScanner reads your students’ handwritten quizzes and tests and drafts marks, partial credit, and comments against a rubric you check and approve. Each student gets a one-page feedback sheet: what went well, where marks were lost and why, and what to work on next. You review every draft and decide the final marks. The time you save goes into what happens after the quiz comes back.

We’ll help you set up your first assessment. After your trial, $49 CAD/month plus HST per teacher.

  • Partial marks and worked solutions
  • Flags uncertain answers for review
  • Works with the paper tests you already give
A stack of scanned papers becomes reviewed marks and a printable feedback sheet. SCANNED FLAGGED 3 / 4 · METHOD OK 24/30

  • Built in Canada

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.

1. 2x + 6 = 14
2. 2x = 8
3. x = 3 arithmetic slip
method correct → 3 / 4 on this rubric
  • Partial marks take time

    Deciding partial credit takes longer than checking a final answer.

  • Many valid forms

    Factored, expanded, mixed number, decimal. Each deserves credit unless the question asks for a form.

  • Steps matter

    The worked steps carry the learning, not just the last line.

  • Handwriting is messy

    Some pages are genuinely hard to read. A model shouldn’t just guess.

  • Feedback is easier to use fresh

    Students can act on comments more easily while the topic is still current.

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

See misunderstandings while the unit is still going, and decide what needs another look.

End-of-unit

Summative tests

MarkScanner does the repetitive first pass. Your marking time goes to the answers that need your judgement.

How it works

From a fresh test to graded feedback, in five stages

  1. 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 edit. Nothing is final until you approve the rubric and the marks.

  2. 02 · Print

    Print on regular paper. No custom booklets or special paper. Tests you upload stay as they are; MarkScanner-generated tests include small page markers for reliable scan grouping.

  3. 03 · Scan

    Scan the finished class set in one upload. A photocopier's scan-to-PDF works best. MarkScanner works out which pages belong to which student, and asks you when it isn't sure.

  4. 04 · Grade

    Draft marks and per-question comments appear. You review every answer, adjust where you disagree, and approve.

  5. 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

    MarkScanner does the first pass. Your time goes to the flagged answers and the judgement calls.

  • Return feedback sooner

    Get tests back while the unit is still current for students.

  • One approved rubric for every paper

    Every paper is marked against the rubric you approved, and you see every comment before it goes out.

  • Printable one-page student feedback

    Grades, comments, and next steps on a single sheet per student.

  • Spot class-wide patterns

    See which questions cost the class the most marks, so you know where to look first.

  • 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.

Work MarkScanner can’t read clearly, and answers where its draft looks doubtful, are flagged for your review. An answer without a flag can still be wrong, so every mark and comment is editable, and nothing is final until you approve it. 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 judgement 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 written feedback that’s hard to write by hand for thirty papers in a row.

  • Grade, per-question comments, strengths, next steps.
  • Editable before print: rewrite any comment in your own voice.
  • Print & staple to the returned paper.

Class insights

See where to look first

Every paper is marked against the rubric you approved, and you review the results, so the class summary reflects the standard you set. See which questions cost the class the most marks and which comments came up most often, then open the responses behind them to decide what needs another look.

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]

Questions

Questions teachers ask

Is MarkScanner fully automatic?
No. It suggests marks and comments; you review, adjust, and approve before anything is finalised.
Does it handle messy handwriting?
It’s built for handwritten work. Work it can’t read clearly is flagged for your review instead of being silently guessed. An unflagged answer can still be wrong, so you review the drafts before approving.
Can I export grades to my gradebook?
Yes. You can download a CSV of the class results and drop it into whatever gradebook you already use.
