One More Greedy Triangle Activity, and A Little More Fun With Geometry

I was about to clear the marshmallows, and toothpicks away, when I came across one more Greedy Triangle inspired activity, from Mrs. Coon's Team.


I laid out what was left of our stale marshmallows, along with a few more toothpicks, and our polygon, lacing cards, from the other day.


The children came and went, forming polygons at their leisure.

Naturally, we ended up with a few more tetrahedrons too, because those are just fun to make. In fact, we spent some time forming them out of letter sized envelopes, as well, following instructions from Enchanted Learning (click the link to view the instructions).


I did the measuring, and cutting...


...and then traced, and numbered the sides...


...for the children to color, before they folded them together, into place.


It turned out to be a great way to reinforce the concept, of the number of faces of the shape.

Finally, just to cap it all off, we watched They Might Be Giants' "Nonagon" song (click the link to view it on YouTube). Thanks to Kimberly of All About (my) Boys, for recommending it.

It's great to be a homeschooler.
