Norm asked, "which came first, mult, or div.?"
In my 5th grade classroom text, mult. and div. are separate chapters with
mult. coming first. With the learning of basis facts, I teach them as
related with triangular flash cards showing the 3 digits of a fact family.
For example, one card will have 6 in one corner, 7 in one corner and 42 in
the 3rd corner. Now we can see that 6 *7 = 42, 7 * 6 = 42, 42 / 6 = 7, and
42 / 7 = 6. Kids grasp the connection and relation between mult. and div.
without having to stress one operation over the other.
