A Valentine's Puzzle

On Thursday, Feb. 12th I gave the students a puzzle.  They each were given a 4 inch circle and a 4 inch square.  I asked them to cut them out and try to put them together in such a way to make a heart. Then I told them they should make one cut to help but they still needed to use all of the circle and square.  Some got it but most got frustrated.  It was a good challenge.  After we looked at the answer on paper, we made one with cake!


Here's the puzzle:

Then we put in together with an 8 inch square cake and an 8 inch circle cake.

It was a delicious puzzle.
