Snowflakes are an example of geometry in nature.  Each snowflake has its own geometric pattern, repeated in radial symmetry. It’s no wonder that snowflakes are a favorite project in my classroom!  All those budding 4th and 5th grade engineers love this project!

We start with a 6″ square of paper, folded into two triangles, make a few snips here and there, and start looping the triangles forwards and backwards to create each snowflake point.  (Step-by-step instructions here.)   It takes 6 points to make a snowflake, so each snowflake is a collaborative effort!  We also learn about geometry with this lesson, because we start with a square, fold it into isosceles triangles, and our cuts are parallel lines that are parallel to the hypotenuse!  If I had a bit longer in class, we could also do a little science lesson about how ice crystals form.  The results are large (1-foot diameter) snowflakes that get a LOT of compliments from everyone who sees them.
