THE HAND CALCULATORYour friends will be amazed when you magically transform your hands into a calculator and multiply on your fingers!
MATERIALS: Pen
PREPARATION: Draw calculator keys on your palms with a ballpoint pen. For example write the number 1 on you left hand under your thumb; number 2 on your left hand under your index finger; write up until you get to your right hand and the number 10 under your thumb. (see diagram below)
PRESENTATION: Tell your friend that she can multiply by 9 on your hands just as she would on a regular calculator. After she enters the numbers and pushes [=], just bend over the finger that is multiplied by 9. The fingers that are standing up tell her the answer.
Example: 9 x 4 = 36 (see diagram)
