Games might look like just fun.  These games support the development of mathematical concepts.  Strategy, combined with mathematical thinking and playfulness, serves a very important purpose. 

It is expected that students will play the same game with you many times, developing variations and extensions that will "push" their skills forward.  When you play these games with your child, it is important to "think out loud" about your strategies.  Try to make the game easy in the beginning.  Success will create confidence.  If your child needs counters, use concrete objects like dried beans.  If you are sorting and counting money, use real coins. Better to have many short positive sessions than one long session. So, most important, keep it short (5 to 10 minutes), positive, and have fun!  Let your child see the "problem solver" within you. Positive attitudes about Math are catchy.
