 Information for Teachers

  • It`s a skill to be practiced for command.
  • To multiply fractions:

Multiplication of Fraction

  • Convert each mixed number into an improper fraction.
  • Multiply the numerators to make the numerator of the new fraction.
  • Multiply the denominators to make the denominator of the new fraction.
  • Simplify the resultant fraction.

Multiplication of Fraction

  • While teaching the lesson, the teacher should consult with textbook at all steps where and when applicable.

Material / Resources

  • We will talk about more multiplying fractions (proper, improper and mixed fractions)



Activity 1

  • Write following points on the board and discuss with the students by giving examples of proper, improper and mixed number fraction.
  • Change all mixed fraction (if any) to improper fraction.
  • Ask how we change mixed number fraction into improper fraction. Ask students to suggest fractions, write fractions on the board.
  • Multiply both the numerators.
  • Multiply numerators of the suggested fractions.
  • Multiply both the denominators.
  • Multiply denominators of the suggested fractions.
  • Write both products as one fraction.
  • Change the improper fraction to a mixed fraction and simplify it if possible.
  • Solve following examples on the board.
  • Solve the above example by explaining each step.
  • Divide students in groups and refer them to textbook exercise for practicing the multiplication of fractions.
  • Call one student from each group to share work of their group with the whole class on the board.


Sum up / Conclusion
  • For the multiplication of fractions:
  • Multiply the numerators of the fractions.
  • Multiply the denominators of the fractions.
  • Place the product of the numerators over the product of the denominators.
  • Simplify the fraction.


  • Write following questions on the board and ask students to solve on the board.
  • Encourage slow worker to come on the board to solve the sums.

Follow up

  • Ask students to solve the following story problem with the help of fractions.
