POW questions one and two seemed pretty simple but thinking about number three was tricky. I decided to break it down. If I draw four squares, I can make any even number of squares greater than 2 with one of them. It makes sense for this number to be an odd number. If I take any odd number and subtract three, I get an even number that I can make inside the remaining square with some variation of the 4 or 6 square examples on the board. However, 5-3 = 2 which (if you made it through #2) was already shown to not work!
