Equilateral Triangle Puzzle (original post)

At the start of the school year, I came across this tweet by @MathEqualsLove…

I loved the Equilateral Puzzle, so I finally got around to sharing it with teachers during a workshop I was leading. They loved it.

I changed the problem slightly to create multiple levels of success…

One teacher said he’d even try it with his continuation high school students. True to his word…he did…and sent me these photos of joyful students persevering.

Give it a try yourself!
