How to build a custom math trivia set

Printable math trivia sheets rarely match the unit your class is studying, so a generic download can waste study time. You can instead turn your own geometry, fraction or algebra notes into math trivia questions with pictures in a few minutes by uploading them to DeckOwl.

Upload a textbook photo, slide deck or PDF with diagrams and labeled figures.
Choose multiple choice for quick trivia rounds or short answer for deeper recall.
Read the explanation after each answer to see which step or property you missed.
Export to PDF or DOCX for a printed review sheet on Plus, or to QTI and Moodle XML on Pro.

Example geometry and fraction trivia questions with diagrams

How many lines of symmetry does a regular hexagon have?6. A regular hexagon has 3 lines through opposite vertices and 3 through the midpoints of opposite sides.

A square and a circle have the same perimeter. Which shape has the larger area?The circle. For a fixed perimeter, a circle encloses more area than any other shape.

How many edges does a triangular prism have?9. Two triangular faces contribute 6 edges, and three vertical edges connect them.

A pie chart slice measures 90 degrees. What fraction of the whole circle is it?One quarter. A full circle is 360 degrees, and 90 divided by 360 equals 1/4.

Which of 48, 49 or 50 is a perfect square?49. It equals 7 times 7, and neither 48 nor 50 is the product of a whole number with itself.
