Lesson 4: Interpreting and Computing Division of a Fraction by a Fraction—More Models
Student Outcomes Students use visual models such as fraction bars and area models to divide fractions by fractions with different
denominators.
Students make connections between visual models and multiplication of fractions.
Classwork
Opening Exercise (2 minutes)
Begin class with a review of equivalent fractions. Ask each student for a new example of an equivalent fraction. Students need to share how they know that the new fraction is equivalent to the old fraction.
Opening Exercise
Write at least three equivalent fractions for each fraction below. Be sure to show how the two fractions are related.
a.23
Sample solutions include 46,69,812,1015,1218.
b.1012
Sample solutions include 56,1518,2024,2530,3036.
Example 1 (3 minutes)
For the first example, students will be asked to solve a word problem using the skills they used in Lesson 3 to divide fractions with the same denominator.
