Multiplying Fractions
Watch this video to review how to multiply fractions using an area model (and a KitKat - Yummy)!
Here is a video that reviews how use basic multiplication to multiply a fraction by: another fraction, a whole number, a mixed number and it includes a practice question for you.
Here is a pic of one group's work in class today. Tejasv suggested that to figure out the fraction,
of pie that Rob ate, you should divide 100 by 12.5.
Why does this work to find the denominator for the fraction of pie he eats?
Record your answer in the comments here and remember to include your name:)

Multiplying Fractions with a Model
Here is a video with the kit kat lesson on it from class today.
What is a possible way that someone might get confused when they are trying to multiply fractions with a model?
What do you know about the answer to a multiplication question when the numbers you are multiplying are fractions? (Hint- How is it different than multiplying 2 whole numbers?)
