Why build your own shape flashcards

Geometry units move fast from polygons to solids, and a generic printed sheet rarely matches what your teacher covers. printable shape flashcards work best when they come from your own lecture slides or textbook pages. Upload the file or a photo of the page, and DeckOwl reads the text and writes cards you can review with spaced repetition.

Cards match the exact vocabulary in your own lesson
Front-and-back cards cover names, properties and formulas
Spaced repetition schedules review for the shapes you miss
Export to PDF on Plus when you need a printed set

Frequently asked questions

How many flashcards should I make for a geometry shapes unit?

Aim for one card per term or property, such as sides, angles, faces and formulas for each shape in the unit. Most units fit comfortably in 30 to 60 cards, and you can split them into sets by shape family.

What should a shape flashcard show on the front and back?

Put the shape name or a property question on the front, such as how many faces a prism has. Put the short answer on the back, and include the formula when one applies, such as the angle sum for a polygon.
