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.
