Stoichiometry problems are easier to solve with the mole bridge which shows students how the balanced chemical equation connects the micro- and macroscopic worlds.This resource includes choices of page to hand out to students, print (and laminate) for class sets, hints on solving stoichiometry problems (including walking all the way across the bridge so you don't swim with sharks), a simple way to grade stoich problems, and a bridge for molarity problems.
