Beat the Calculator

Materials: a calculator; a penny or a random-number generator (optional); 1 Fact Power Table (optional)

Number of Players: 3

One player is the "Caller," a second player is the "Calculator," and the third is the "Brain."

The "Caller" selects a fact problem by dropping a penny on Game Master 7 or by using a random-number generator to create an addition-fact problem. The "Calculator" then solves the problem with a calculator while the "Brain" solves it without a calculator. The "Caller" decides who got the answer first.

Players trade roles every 10 turns or so.
