Math Monday: How Many Triangles

Today's math prompt was fitting, as we used chopsticks leftover from our Chinese New Year celebration.
I first saw this prompt, 'How many triangles?' from a lovely Russian site called KokokoKids
No Russian required as the beautiful pictures are self explanatory.

I divided the sticks into 2 piles of nine and separated the mathematicians so they could not see each others work. We talked about there being many possibilities and no single conclusion, as long as all of the triangles accounted for had...
~3 sides
~3 corners (touching sticks)

Ms. O continued to amaze me and compete against herself, trying to beat her own numbers.
And mine!

We ended our session with this lovely book, 'Not a Stick'.
