Why a picture-based quiz helps with math

Many math topics depend on a figure, graph or labeled diagram, and a picture math quiz tests whether you can read that figure before you calculate. Generating one from your own notes means the questions match the examples and notation your class actually uses.

  • Questions drawn from your own math material rather than a generic bank
  • Explanations that show the steps behind each correct answer
  • Multiple choice, true/false and short answer in one generation
  • Exports to PDF and DOCX on the Plus plan
Example picture-based math quiz questions
A rectangle is 6 cm wide and 4 cm tall. What is its area?24 square cm, because area equals length times width, so 6 × 4 = 24.
A right triangle has legs of 3 and 4. What is the length of the hypotenuse?5, because 3² + 4² = 9 + 16 = 25, and the square root of 25 is 5.
Do the three interior angles of any triangle always add up to 180 degrees?True, because in Euclidean geometry the interior angles of a triangle always sum to 180 degrees.
A pie chart slice covers 90 degrees of the full circle. What fraction of the pie is it?One quarter, because 90 out of 360 degrees reduces to 1/4.
On a bar graph, one bar reaches 12 and the next reaches 8. What is the difference?4, because you read both values from the axis scale and subtract 8 from 12.

Photos of pages

Snap a textbook page or worksheet and upload the image. DeckOwl reads the text with recognition, so typed numbers and labels usually come through best.

Three question formats

Get multiple choice, true/false or short answer questions, each with an explanation of why the answer is correct.

Export when you need it

Plus users can export to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes or photos of math pages.

Choose a question type

Pick multiple choice, true/false or short answer, then generate the quiz.

Study and check

Answer in the browser, read the explanations, and export the quiz if your plan includes it.

Photos of pages are read with text recognition, so check that the numbers and labels came through correctly before you study. Redraw the figure in your own notebook when a question depends on it, since that step builds the skill the quiz is measuring.

Frequently asked questions

How do I study math problems that rely on diagrams?

Redraw the figure, label the values you know, and write the rule you need before choosing an answer. Then compare your steps with the explanation to see where your reasoning differed.

How many questions should I aim for in one math study session?

Keep each session focused on one concept so you can review the explanations properly. Repeat questions you missed on a later day, since spacing your practice usually helps more than one long run.

Can I export a math quiz to PDF or Word?

Yes, the Plus plan includes PDF and DOCX export. The free plan lets you study in the browser without exports.

Does DeckOwl read math from photos of textbook pages?

Yes, photos are read with text recognition. Check the generated questions against the original figure, because diagrams and handwritten marks may not be read perfectly.
