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.

Have they changed their mind about math being fun?

That is so cool.

Very cool.

We did a stArt project with The Greedy Triangle a while back. I look forward to reading what you did with it.

Christy - I'm glad you said that. I knew someone I read regularly had used it, but I couldn't remember who.

If they haven't changed their mind yet about math being fun, at least they must think it's delicious.

So very cute...and sneaky. :)

I haven't heard the word TETRAHEDRON since I taught at Nature's Classroom and taught a class on them!

Wow! I love this project! Can't wait to try it!

This is just awesome. I love the hands-on solid geometry lesson - better than any manipulative you could ever buy.

Nicole said...

Love this! We are going to make these this week (or as soon as I get some more powdered sugar:) Thanks!

Looks delicious. I like how you do several different projects on one theme.
