Question:
Is there a great hands on way to explain division of fractions to
sixth graders without the age old, "it's not for you to reason why, just
invert and multiply?"

Replies:
Division is usually defined as multiplication by reciprocals or
inverses. In this case, starting with (m/n)/(p/q), multiply the numerator and
denominator by q/p and simplify the denominator to 1 and you have proved it.
I do not know how this is great or hands on, but it is an idea.
