How to run this board

This board covers the proportional reasoning that runs through middle school math: writing ratios three ways, finding unit rates and best buys, solving proportions, converting between fractions, decimals, and percents, and working percent problems like discounts, tax, and tips.

Calculators or not is the first decision; most of these clues use friendly numbers, so leaving them out keeps the mental math honest. Either way, have every student work each clue on paper, and let a team buzz only once they can show their setup.

The Real-World Percents column is the one students will use outside school. If time is short, play it before the Proportions column rather than after.
