Lesson Planning of Division of Fraction
Students` Learning Outcomes
- Divide fraction by a whole number
- Divide a whole number by a fraction
- Divide a fraction by another fraction (proper, improper and mixed fractions)
Information for Teachers
- You know how to call the numbers in division?
- To divide 2 fractions multiply the divided by the reciprocal of the divisor.
- Reciprocal of a fraction is [1÷fraction] and it turns the fraction upside down
- Encourage students to help each other in learning these skills.
- While teaching the lesson, the teacher should also consult with textbook at all steps where and when applicable.
Material / Resources
Writing board, chalk/marker, duster, chart paper, textbook
- Tell story problems that involve division with whole number on the board.
- Maria has a dozen biscuits. These biscuits have to be shared equally with 6 of her family members. How many biscuits will each of her family member get/?
- Salma wants to get jogging in 2 hours; she can jog a total of 8 miles. How many miles cn she jog in one hour?
- Mother made 36 chocolate chip cookies. How many jars holding 9 cookies each can she fill?
- One day Fiaz collected 60 eggs from his hens on the farm. How many boxes holding 6 eggs each can he fill?
- Ask the students to use any strategy they choose to solve these problems and to show their work.
- Ask the following questions: as;
- What kind of problems are these, Addition, Subtraction, Multiplication, or division? (Expected answer would be as; Division)
- Tell students that today we will divide fractions the way we have done multiplication of fractions.
Size of chocolate = 1 whole
number of pieces required = 5
size of each piece = 1 ÷ 5
size of each piece = 1 x (1 / 5)
- Reciprocal of a fraction is 1 fraction, or simply invert the fraction.
- To multiply;
- Change mixed number fractions into improper fraction.
- Take invert of the second fraction
- Multiply the fractions and convert into mixed number fraction if answer comes in improper fractions.
- Divide students in groups and provide them two dice in each group.
- Ask students to roll the dice and make a fraction with numbers they get.
- Again roll and make another fraction. Divide both fractions and get the answer.
- Allocate 10 minutes and tell them that the group with maximum questions within the time will win the round’
- Give following questions to solve in their notebooks as homework.
- How many halves are there in six-fourth?
- You have 12 ½ cups of flour left in the cupboard. A tray of biscuits requires 1 2/3 cups of flour. How many trays of biscuits can you make?
- An airplane covers 50 miles in 1/5 hours. How many miles can the airplane covers in 5 hours?
