Unit 5, Lesson 9# Multiplication and Division of Fractions: Lesson 9 (Multiplying a Fraction by a Fraction)

Match Fishtank 50 min(s)

In this lesson, students will multiply a fraction by a fraction with more complicated subdivisions using an area model. As the Progressions state, For more complicated examples, an area model is useful, in which students work with a rectangle that has fractional side lengths, dividing it up into rectangles whose sides are the corresponding unit fraction. For more complicated examples in todays lesson, students will trade the tape diagrams and number lines they've been working with for much of the unit thus far for an area model in this lesson and subsequent ones.
