Do you have enough math smarts to beat a calculator? Could the type of math problems you're given have anything to do with your chances? Try your skills in the Brains Versus Calculator game.

Materials: calulator (provided below); a penny or other marker; math problems (follow links below)
Number of Players: 3
Directions:
1) One player is the "caller," a second player is the "brain," and the last player is the "calculator."
2) Make a list of math problems or print out the problems we have provided [Primary Problems (ages 5-8) or Intermediate Problems (ages 8-12)]. If you make up your own, choose your problems based on your ability level. Primary kids should stick to 1 digit adding and subtracting while older kids should include multiplication and division problems.
3) Have the "caller" drop a penny or some other marker on the problems. The "caller" calls out the problem.
4) The "calculator" MUST use the on-line calculator shown below to solve the problem (even if they know the answer) and the "brain" must figure out the answer in their head. Say the answer out loud as soon as you can.
5) The "caller" decides who said the answer the fastest.
6) Switch jobs every 10 problems or so. Good luck!
7) How did you do? Work on building your fact power so that you can beat the calculator.
