Around this time of year, I was typically teaching stoichiometry, a big challenge for the chemistry student. My favorite approach to stoichiometry is the factor-label method because it was less memorization and less room for error.
This is very unit based, a habit I encourage in students. For example,
5 grams Cu x 1 mole Cu/64 grams Cu = 0.08 mole Cu
Yes, it's the same as memorizing to divide when converting grams to moles, but there less chance for error when a student is in the habit of making sure the units cancel.
There are various "maps" that provide an image of the multiply/divide route, and they are useful.
Let me know some of your mole successes and challenges!
