I did learn a new exercise for math. We all know skip counting, 2,4,6,8..... Have you tried having your kid skip count backwards? Start at 20 and count backwards to 0 by 2. Start at 18 and count backwards by 3 to 0. And so on. She discovered that counting backwards by six is easy if you can count backwards by 3. Somehow she never noticed the relationship when she was doing it forwards. I think this will be great for us. I am trying to teach multiplication and solidify subtraction. This is perfect.
