Esteban ...jump right in.  The water's fine.

As you say, there can be one method [algorithm] or another to reach a result,
but what they need to understand is not som uch the method, but that it is the
means to an end .. in its simplet terms, to find out how many times one portion
will divide another.  Waht matters is the understanding of the interplay of
pattern in multiplication anddivision.  For an understanding of ratio and
similarity and so on in later years, what is important is a knowledge and
understanding of equivalent fractions.

With regard to your comment about the big picture, I'm with you 100%.  Too often
the young are subjected to concepts beyond their understanding.  They need to
know the roots, stem and leaves before knowing the entire plant.
