Lesson 3 Student Outcomes

• Students use visual models such as fraction bars and area models to show the division of fractions by fractions with common denominators.
• Students make connections to the multiplication of fractions. In addition, students understand that the division of fractions require students to ask, “How many groups of the divisor are in the dividend?” to get the quotient.


Lesson 3 Classwork

Lesson 3 Opening Exercise

Draw a model to represent 12 ÷ 3.

How could we reword this question?

If we divide 12 into three groups of equal size, what is the size of each group?
If we divide 12 into groups of size 3, how many groups would we have?
If I have 12 chickens and I put 3 chickens in each cage, how many cages will I need?
If I have 12 flowers and I place 3 flowers in each vase, how many vases will I need?




Example 1

Draw a model to show the division problem.
8/9 ÷ 2/9

Example 2

Draw a model to show the division problem.
9/12 ÷ 3/12

Example 3

Draw a model to show the division problem.
7/9 ÷ 3/9

Exercises 1–6

For the following exercises, rewrite the division problem. Then be sure to draw a model to support your answer.
1. How many fourths are in three fourths?
How are Example 2 and Exercise 1 similar?
How are the divisors and dividends related?
What conclusions can you draw from these observations?
2. 4/5 ÷ 2/5
3. 9/4 ÷3/4
4. 7/8 ÷ 2/8
5. 13/10 ÷ 2/10
6. 11/9 ÷ 3/9


 


Lesson 3 Exit Ticket
Draw a model to support your answer to the division questions.
