Odd to Win!
You and your partner need to have a total pile of 15 cubes. Whoever has the most siblings goes first. Taking turns you and your opponent take cubes from the pile. However, you can only take 1, 2, or 3 cubes on your turn. When there are no more cubes in the pile, you count your cubes. Whoever has an odd number of cubes wins. Put the cubes back in the pile and start again. This time the other player goes first.
(As you play think about odd and even numbers.)
Hint: You need to plan and have to develop a strategy to win. Be ready to share your strategy with the group if you have a good one.
