A lesson for grade 5 math - I explain how fraction multiplication and the area of rectangles relate to each other. Basically, to find the area of a rectangle with fractional side lengths, we multiply the fractions (of course). 

Also, the visual model of a rectangle divided into parts provides a neat illustration of fraction multiplication. We can basically model fraction products as rectangular areas.

This fifth grade math topic is also explained (along with practice problems) in my book Math Mammoth Fractions 2 at http://www.mathmammoth.com/fractions_2.php - available both as an inexpensive download ($5.75) and as a printed copy.
