# Multiplication of Fraction

Lesson Planning of Multiplication of Fraction (Proper, Improper & Mixed)

Subject Mathematics

Students` Learning Outcomes

• Multiply two or more fractions (proper, improper & mixed).

Information for Teachers

• It`s a skill to be practiced for command.
• To multiply fractions: • 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. • While teaching the lesson, the teacher should consult with textbook at all steps where and when applicable.

Material / Resources

Writing board, chalk, marker, duster, chart paper, textbook

Introduction

• Ask following questions to elicit previous knowledge and announce about todays` lesson.
• What is multiplication?
• What did we do about multiplication of fractions in the last class?
• Shania has to read 10 books, she is done with half of them, and how many are left?
• I have 40 questions to do, I am done with ¾ of them, and how many I have done?
• 1 / 7 what type of fraction is this?
• 9/5 what type of fraction is this?
• What is 6 x 2/3?
• 3/2 x 4/5 =? This is what we are going to explore today!
• We will talk about more multiplying fractions (proper, improper and mixed fractions)

Development

 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.

Assessment

• 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.
