About the projects
These craft projects are fun to make, but also teach some basics of
geometry.
Learn about radial symmetry by making
paper snowflakes.
Try to solve puzzles using the basic geometric shapes in a set of
tangrams. Take geometry to the third
dimension with Platonic solids, and have
fun finding hidden surfaces with flexagons!
For even more geometric fun, see the roundup of crafts based on
Triangles!
The projects range in difficulty from VERY EASY to AVERAGE.

Learn how to make a flexagon, a
most fascinating geometric toy! Flexagons are folded paper polygons that have the neat feature of changing
faces as they are flexed. With a quick fold, change a flexagon that is green and yellow to green and blue,
then to yellow and blue.

In this project, make
four
of the five Platonic solids—cube, tetrahedron, octahedron, and icosahedron. These geometric models can be used
for things beyond learning about solid geometry. Decorate them and make a colorful mobile
or use them as gift boxes.

In this project, see how to make
mini-boomerangs that really fly and return to the thrower!
These tiny boomerangs are launched with a flick of a finger and can
be played with inside. The project includes printable
patterns and ideas for aerodynamic experiments.
VERY EASY

In this project, you'll make the
tri-tetraflexagon which is one of the simplest and easiest to make
flexagons. It looks like a simple paper square with a front and a
back, but hidden inside is another side (or face) that is revealed
by folding the square in half and flexing it.

Fold a hexa-hexaflexagon and watch it transform! This six-sided,
six-faced flexagon is a fun and challenging geometric project for
all ages. It looks like an ordinary hexagon, but hidden inside are
four more sides that reveal themselves as you flex it. Our project
includes easy-to-follow instructions and patterns, and is perfect
for anyone who loves puzzles, games, or just having fun. The project
also includes patterns for tetra-hexaflexagons and
penta-hexaflexagons.

Learn how to make paper snowflakes. This project includes
patterns for several different snowflakes, including Aunt Annie's favorites. You will also learn about the symmetry found in every snowflake.

Unlock the challenge and creativity of Tangram puzzles! Originally
from China, these brain teasers have captivated minds for centuries.
This craft offers everything you need to get started, including free
printable Tangram patterns for making your own set and
puzzle sheets to test
your skills. Fun for puzzlers of all ages!
VERY EASY
Description ↓
In this craft project, learn a simple technique
based on circles for making all five Platonic solids—tetrahedron, octahedron, icosahedron, cube, and
dodecahedron. The solids can be also be decorated and used as giftboxes
or to make a 12-sided, dodecahedron calendar.
EASY
Cut five-pointed stars from red, white and blue paper and string them
to make a garland! Use the garland to decorate for Memorial Day, Flag
Day or the Fourth of July. This is a great craft for kids and
families.
EASY
Learn an easy way to make
snowflakes from tissue paper. With this technique you can make a whole
flurry of snowflakes in a hurry! Using tissue paper makes cutting
through many layers easier, but you can use any lightweight paper you
like.
