Pooh and I were working on his math lessons using Khan Academy the other day and he ran into a little trouble when it was time to learn polygons.

He’s six, after all.

For our free printable flashcards series this week, I thought I’d whip up a set of Free Printable Flashcards: Polygons!

This set includes the eight simple polygons, which makes it easier for little ones to get an introduction to geometry.

These free printable polygon flashcards are awesome for introducing preschoolers and kindergartners to basic shapes.

But since they include more complex shapes as well, they’re a good review for elementary students too!

If you enjoy using these with your students, check out some of our other math printables, including Amusement Park Addition Flashcards and our Aquarium Arithmetic Printable Pack!

**What’s In the Free Printable Flashcards: Polygons Set?**

To use these flashcards, you’ll need the following: (*This post contains affiliate links. For details, see our Disclosure Policy*.)

- Printer (with ink)
- Printer paper
- Scissors
- Laminator (good for cards you plan to reuse)

The word “polygon” actually means multi-sided shape.

So any shape with “many” sides counts as one. In this set, though, we’re focusing on shapes with three to ten sides.

In the set, you’ll find flashcards for all eight simple polygons:

- Triangle (3-sided shape)
- Rectangle (4-sided shape)
- Pentagon (5-sided shape)
- Hexagon (6-sided shape)
- Heptagon (7-sided shape)
- Octagon (8-sided shape)
- Nonagon (9-sided shape)
- And Decagon (10-sided shape)

There’s a set of all eight with words and without for quizzes or playing a game of concentration. Take a few minutes to quiz the kids with the unlabeled cards!

Or have them count the sides of each shape and guess which it is!
