How a photo becomes a math quiz

Many students have phones full of math quiz images, photos of worksheets and textbook pages that never get used because they are hard to study from.

  • Works with photos of worksheets, textbook pages and printed notes
  • Multiple choice, true/false and open questions with explanations
  • Free plan includes 3 generations per month, with no exports
  • Plus and Pro plans add exports for PDF, DOCX, and Pro adds QTI 2.1 and Moodle XML
Example algebra questions for a math quiz
Solve for x: 2x + 6 = 14x = 4. Subtract 6 from both sides to get 2x = 8, then divide both sides by 2.
True or false: the derivative of sin(x) is cos(x).True. Differentiating sine gives cosine, a standard result from calculus.
What is the area of a triangle with base 10 and height 6?30. Area is one half times base times height, so one half of 10 times 6 is 30.
Simplify: 3(x + 4) - 2xx + 12. Distribute the 3 to get 3x + 12, then subtract 2x to combine like terms.
Is 91 a prime number?No. 91 equals 7 times 13, so it has divisors other than 1 and itself.

Reads photos of pages

Take a picture of a printed worksheet or textbook page and DeckOwl reads the text with text recognition. Check the recognized text before generating for the cleanest questions.

Question types that fit math

Choose multiple choice, true/false or open questions. Each answer comes with an explanation so you can see the steps behind the result.

Study in the browser

Take the quiz right after generating it, then review the questions you missed. The free plan includes 3 generations per month, and exports require a paid plan.

How it works

Upload a photo or file

Add an image of your math page, or upload a PDF, DOCX, PPTX or plain text notes.

Pick the question type

Choose multiple choice, true/false or open questions, then generate the quiz.

Practice and review

Answer the questions, read the explanations, and retry the ones you got wrong.

Once the text is read, DeckOwl writes questions based on the problems on the page. Each multiple-choice, true/false or open question includes an explanation, so you can check the reasoning rather than only the final number.

Paid plans can export the quiz as PDF or DOCX, and Pro adds QTI 2.1 and Moodle XML for learning systems.

Frequently asked questions

How many questions should a math quiz have?

Ten to fifteen questions is a good range for a single study session on one topic. Shorter quizzes make it easier to spot which step you keep getting wrong.

How should I study after taking a math quiz?

Redo each missed problem on paper without looking at the answer first. Then read the explanation and try a similar problem to confirm the method stuck.

Can I use photos of handwritten math problems?

Photos of printed pages are read most reliably, and clear, well-lit images work best. Review the recognized text before generating, since handwriting can be harder to read.

Do I need a paid plan to export my quiz?

Yes, exports are paid features. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML.
