I thought of a great math puzzle today. Here it is:
Every year before my son's birthday we display a clown ornament (like the one shown at right) on our front lawn that counts down the days until his birthday by using numbers that are painted on two blocks. There are six sides to each block. One number is painted on each side of the two blocks, but some numbers are used more than once. How can you arrange the numbers on two blocks to create the maximum number of days that can be counted down?
