What they don't teach (and should) is that sometimes in the real
world it's easier to leave the fraction unreduced and work with it.
Sorry, can't teach that. Teaching something supplies the knowledge,
but learning when or how to apply that knowledge requires
participation.
You can teach that in theory and suggest they try it on homework (Ooh,
story problems!) You can even require they use that method on the
homework and take off points if they don't. (Give them points for a
correct answer if they use another method, but not all the points.)
John measures a board's thickness and it's 6/8". He wants to add a 1/8"
thick border around the outside. How thick will the final piece be?
