I think the best way is to produce comparison sentences, probably using the passive voice so that the determiner/quantifier is the subject. There's a good example in Michael Vince's Intermediate Lang Practice (p.141)
All (of ) the tickets for the match have been sold
Many of
Some of
None of
These form a cline from Most to Least. How about bringing along some tickets? Hold up numbers of tickets and ask How many ? Some will respond with numbers initially, so you'll need to keep drawing them back to the sample setences.
You can use the ngeative forms No, Not any, Not Many /Not Much in the same way, I guess.
But clearly you need to teach the positive forms first.
Any help?
