Here's a game that helps little ones learn math concepts "more" and "less."
First, have the kids close their eyes. Then hold up a number of your fingers. "How many fingers am I holding up?" you ask. Then your child guesses, while keeping eyes closed. You respond to each guess with "More," "Less," or "Absolutely right!"
Once your kids get the concept, you can close your eyes and take a shot at guessing how many fingers they're holding up. (During a recent run through of this game, my boy really surprised me. After I guessed all the possible numbers—1, 2, 3, 4, and 5—and was told that I was wrong every time, I opened my eyes to discover he was holding up all his fingers on both hands. He was delighted, of course, and I was foiled again.)
Have fun playing this learning numbers game with your kids, but whatever you do, for your own safety and the safety of your self esteem, don't try to play this one with any teenagers!
