1. Module 2 – Lessons 3 & 4 Lesson Topic: Interpreting and Computing Division of a Fraction by a Fraction – More Models
Lesson Objectives: I can…
Use fraction bars and area models to show the division of fractions by fractions with common denominators
Make connections to the multiplication of fractions.
I can understand that to get the quotient when dividing fractions, I must ask “how many groups of the divisor are in the dividend?”.

2. Opening Exercises
1. Draw a model to represent 12 ÷ 3 2. Write at least 3 equivalent fractions for the fraction below 2/3

3. Example 1:
What is 8/9 ÷ 2/9? Take a moment to use what you know about division to create a model to represent this division problem.

4. Example 2:
Molly purchases 1 3/8 cups of strawberries. This can also be represented as 11/8. She eats 2/8 cups per serving. How many servings did Molly purchase? Create a model to find the answer.

5. Example 3:
3/4 ÷ 2/3 What is this question asking? Why is this question more difficult to model than the previous questions? How do we solve this problem?

6. Independent Exercise 1:
Rewrite the division problem and draw a model to support your answer. 3/4 ÷ 1/4

7. Independent Exercise 2:
Rewrite the division problem and draw a model to support your answer. 9/4 ÷ 3/4

8. Independent Exercise 3:
Solve the following problem with a model and explain your answer 6/2 ÷ 3/4

9. Independent Exercise 4:
Solve the following problem with a model and explain your answer 3/5 ÷ 1/4

10. Closing
What key ideas do you need to know in order to be able to divide fractions by fractions with the same denominator? Fractions with different denominators?
