Why generate your own math trivia

A class warm-up or game night often needs a fresh set of math trivia pictures every time, and a printed sheet rarely matches the topic you just covered. Starting from your own notes keeps the questions tied to the exact methods and diagrams your group is learning.

Turn lecture slides with geometry diagrams into picture-based questions
Add explanations so answers can be reviewed after each round
Create true/false rounds for quick checks before a test
Export to PDF or DOCX on Plus, or to QTI 2.1 and Moodle XML on Pro

Example math trivia questions for a picture round

How many sides does a hexagon have?Six. A hexagon is a polygon with six sides and six interior angles.

What is the sum of the interior angles of any triangle?180 degrees, because the three angles of a Euclidean triangle always add up to a straight line.

What is the sum of the whole numbers from 1 to 100?5050. Pairing 1 with 100, 2 with 99 and so on gives 50 pairs that each total 101.

How many faces does a cube have?Six. Each face is a square, and a cube has six of them.

Which prime number is also even?2. Every other even number is divisible by 2, so it cannot be prime.

Generate the full set

Built from your material

Questions come from the diagrams, formulas and examples in your own files, not a generic bank of puzzles.

Explanations for every answer

Each question includes a short explanation, so players learn why the answer is right, not just what it is.

Multiple formats

Choose multiple-choice, true/false or open questions, and study the set in the browser or export it.

How it works

Upload your files

Add a PDF, DOCX, PPTX, text file or a photo of a page. Photos are read with text recognition.

Choose a question type

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

Play or export

Study in the browser on the free plan, or export to PDF or DOCX on Plus, and QTI 2.1 or Moodle XML on Pro.

Picture-based questions work well because they ask learners to connect a shape or diagram to a rule, such as identifying a polygon or spotting a right triangle. Write the prompt to describe the picture clearly, then let the explanation reinforce the idea.

Frequently asked questions

What makes a good math trivia question about shapes?

A good question names one property the learner must recall, such as the number of sides or the angle sum. Keep the wording short so the answer depends on the math, not on reading speed.

How do I make picture trivia easier to remember?

Pair each picture with one rule and a short example, then repeat the questions after a day or two. Spacing the review helps the rule stick better than one long session.

Can I export the quiz to PDF or Word?

Yes, PDF and DOCX export are included with the Plus plan at $99.90/year or $9.99/month. QTI 2.1 and Moodle XML export are available on the Pro plan at $14.99/month.

Do I need a credit card to try it?

No. The free plan includes 3 generations per month and lets you study in the browser without a card.
