Division of Fractions Taught Conceptually, part 2
Reciprocal numbers are taught by looking at measurement divisions with a dividend of 1 (e.g. 1 divided by 3/4). Then the procedure is generalized to any fractional dividend, so that we arrive at the common shortcut for division of fractions (the shortcut of flip and multiply). These steps effectively justify the rule for dividing fractions to the students.

I have used the Math Mammoth Blue Series for a few years. They are great for students who need help with particular topics - multiplication, fractions, geometry, etc - whether they are homeschooled or go to traditional school. The workbooks are a great value. I love the explanation of fraction division seen in these videos, and hope to see more.
