Equivalent with "Fractions. Smart Pirate"

Balance a bridge with equal buckets of fireworks to allow the pirate to cross.  Children are presented with a fraction, for example 2/3, and need to select a fraction with an equal value, such as 4/6, to balance a bridge.  If they are correct the bridge will balance and the pirate can cross.  An incorrect answer results in the crackers exploding.
