find unknown numbers.

3. What’s my number operation?
Mental Activity
What’s my number operation?

4. One child wears a headband with a number attached to it.
That same person calls out a number to the class.

5. The class multiplies that number by the number on the headband and calls out the answer.
The child with the headband works out what the number on the headband is.
