When multiplying fractions by fractions, students (and parents) often get overwhelmed by the confusion of what is taking place. When we multiply whole numbers, one can easily picture a certain number of whole groups of whole objects (e.g 5 x 2 = five groups of 2 apples each, how many apples in all? 10).
With fractions, it is more difficult to picture what is being said by 1/2 of 3/5. NEVER FEAR!! Mr. V is here!!!! dun da da DUNN!! (insert super hero theme song).
In this tutorial I will show you various ways of conceptualizing (picturing) multiplication of two fractions. So sit back, grab some popcorn, and enjoy some math. And remember... MATH IS COOL!
check out this show me to start off your discussion of multiplying fractions by fractions.
attached is a PDF document with extended practice and a game for you to practice your mental math strategies for multiplying fractions by fractions. You can either download the document and print it out, or practice on a separate piece of paper.
