Gingerbread Tetrahedrons - More Fun With Triangles

We picked up a couple boxes of toothpicks, while we were grocery shopping, so A (age 9) could take our fractal tetrahedron to the next level.


We should have picked up another bag of powdered sugar, too, because G (age 11), decided to make gingerbread tetrahedrons, for our story time snack. We read the Greedy Triangle by Marilyn Burns, but I'll have more on that later.



Just cutting all the equilateral triangles out of the dough was a geometry lesson in itself. In an effort to save dough, and cuts, she quickly discovered six equilateral triangles fit together to form a hexagon.


Since, I don't generally stock up on powdered sugar after the Christmas baking season, I only had enough on hand to make one small batch of frosting for her. It was enough to form nine tetrahedrons.

We (mainly I at this point), used four gingerbread triangles, trimming the bottom triangles, so they would fit snugly together.


Once, the frosting had was set, we formed them into a Sierpinski triangle, of sorts.


Then, we balanced loose triangles on top, just for fun.


As usual, you can find more math themed projects, products, and ideas at the Math Monday link-ups, hosted by Joyful Learner.

It's great to be a homeschooler.
