Yes, I am a gamer.
I love games. I love educational games. And unless I need quiet time, I really don't like the electronic ones. They are like kid crack. Of course, if it is old school Mario on the 80s Nintendo (yes, we still have one), then that is a different story.
But I recently purchased some great games, including Math Dice and Math Dice Jr.
Math Dice is rated for 8 and up.
Math Dice Jr. is rated 6 and up.
Math Dice Tournament kit is targeted 5th grade and up.
There are different ways you can adapt it. First, use paper and pencil. Take turns. Teach calculator skills. Use teams. Keep score. Or Don't. You know your kids, your students, and yourself. Grade and challenge the games based on your ability, versus your age. It is a great way to keep your mind multiplying its neural pathways :)
