We had a number of scientifically decorated, coffee filters, left after making our owls, and the little ones wanted to turn them into snowflakes.
It's a bit early for snowflakes, especially considering our forecast for the week is back into the 90's (hurray for summer!), but I had seen coffee filter snowflakes used in Margaret Kenda's Math Wizardry for Kids, for a lesson in symmetry.
So, we folded them in half (1/2)...
...and in half again (1/4)...
...and again (1/8).
Then, we snipped shapes out of them (my 4 year old needed some help, at this point, because the folded filters were pretty thick).
When we unfolded them to reveal the designs, I pointed out the symmetry in the shapes, and the asymmetry of their original drip-dye coloring.
To stretch the activity, and make the concept of symmetry clearer, I cut the snowflakes in half, mixed them up, scattered them across the floor, and had the girls rematch the symmetrical shapes.
This was an easier concept for E (age 5), than for C (age 4), but they both enjoyed the game quite a bit. And, they loved making snow cone colored, snowflakes.

It's great to be a homeschooler.
