(M5NS-Ic-96.2)
II. SUBJECT MATTER
A. Skill: Dividing simple fractions and mixed fractions
B. Reference: K to 12 Grade 6 Curriculum Guide, RBEC Grade 6 Lesson Guide 2010, pp. 277 - 282
C. Materials: Powerpoint Presentation flashcards, activity cards, charts (old calendars), bond
paper, crayon, strips of newspaper/cloth/leaves
D. Value Focus: Concern for the members of the family.
III. INSTRUCTIONAL PROCEDURE
A. Review:
1. Checking of assignment.
Divide a fraction by another fraction
2. Motivation
Who has a favorite pillow? Do you share your pillow with other members of the
family? If you do, what trait did you show? How often do you change your pillow case?
Why? What kind of cloth is your pillow case made of?
B. Developmental Activities
1. Presentation - Present the lesson through the following.
Use of manipulative in solving problem
Aling Ana has 6 2/5 meters of cloth to sew pillow cases for her sons who love clean
and beautiful pillows. She has to decide the measurement of the materials considering the
following:
a. How many pillow cases each 4/5 of a meter long can she made?
b. How many pillow cases can she make if she will use 1 3/5 meter
long for each pillow case?
Answer the following questions:
a. Who will sew pillow cases?
b. For whom will Aling Ana be sewing pillow cases?
c. What materials does mother have?
d. How long is the material for the pillow cases?
e. If you were Ana’s mother, will you do the same? Why?
Analyzing the problem
a. What does the problem ask to look for?
b. What are the given data in the problem?
c. What are the needed facts to solve the problem?
d. What will you do to arrive the solution of the problem?
2. Performing the activity
Group the pupils in 5 learning teams. Let them answer the problem.
Step 1. Write the fractional number using division.
How many ¼ kg. of sugar can you repack from 2 1/4 kg?
Step 2. Find the reciprocal of the divisor.
Remember that 2 1/4 is the dividend while ¼ is the divisor. To get the
reciprocal of ¼, we think of a number or a fraction that can be multiplied to ¼ so
that the product is 1., the answer is 4/1.
¼ x 4/1 = 4/4 =1 Therefore, the reciprocal of ¼ is 4/1.
Step 3. Change the dividend 2 1/4 to improper fraction.
Then, multiply the by the reciprocal of the divisor. If possible reduce to lowest term.
2 ¼ ÷ ¼ = 9/4 – 4/1 = 36/4 = 9 (¼ kg. of sugar)
3. Processing the activity
How did you find the activity? What did you do with the divisor? Did you change
the operation? What did you do with the mixed fractions? Whole numbers?
Discuss with the pupils how they solved the problem. Provide immediate feedback and
remedial measure to those incorrect answers.
1. 10 ÷5/6 = N 6. 2 ½ ÷ 1/3
2. 1 1/6 ÷ ¾ = N 7. 8 ¾ ÷ 3/5
3. 5/6 ÷ 2/9 = N 8. 6 ¼ ÷ 2/7
4. 5 1/3 ÷ ¼ = N 9. 2 ½ ÷ 1/3
5. 3 ¾ ÷ 2 ¼ = N 10. 1 5/6 ÷ 2/10
