We invented this game yesterday when math got a little bo-ring. I put two numbers on Mark’s face and I tell him the sum. He has to guess the correct combination of addends. There are many combinations for some numbers, so he has to continue guessing until he gets the right one. Sometimes he’ll ask for a hint and I’ll tell him one of the numbers. It’s good fact family practice. He’s pretending to think hard about this one.
Math. It’s good for you.
