Tim and Maria were both very good at checkers, but every time they played
using the same checkerboard and the same sides, Maria argued that the
number of squares on a board with a black corner in the upper right hand
corner was more than the number of squares with a white upper right hand
corner, regardless of the size of the square (in fact, they both thought
they counted them all.) Tim, of course would argue the opposite. If the
only rule they had was to set the folding line of the board halfway
between them, can you tell who was right? How many squares were counted? Does
how the squares were counted make a difference?

Concert Stash
The North Pole elves were hoping Mr.and Mrs.Claus would relax as much as
possible before the Christmas Season, so they convinced them to go to a
concert that cost $25 each. It was their treat. The Elves all had col-
lected a few $10, $5,$1, half dollars and quarters from their own stashes,
but first had to figure out in how many different ways they could come up with
the money for the concert, since each one wanted to give some of
their money. It took them a while, but I bet MathMagicians could come up
with all choices really fast... Well, can you?

Good luck, and happy holidays
