Students` Learning Outcomes
- Verify the Commutative property of multiplication of fractions.
- Verify the Associative property of multiplication of fractions.
Information for Teachers
- There are properties involving multiplication that will help make problems easier to solve.
- Commutative Property: Change the place in multiplication of two fraction does n`t change the product.
- Associative Property: When three or more fractions are multiplied, the product is the same regardless of the grouping of the factors.
- While teaching the lesson, the teacher should consult with textbook where and when it is required.
Material / Resources
Writing board, chalk, marker, duster, chart paper, textbook
- Write following statements on the board and recall the properties of commutative and associative for addition, as; 4 + 2 = 2 + 4, (5 + 3) + 2 = 5 + (2 + 3)
- Which properties are being used? (Expected answer would be as; Commutative and Associative Properties)
- B + a = a + b, (a + b) + c = a + (b + c)
- Now tell that these properties are also verified for multiplication.
- 4 x 2 = 2 x 4 (Expected answer would be as; Commutative Properties)
- (5 x 3) x 2 = 5 x (2 x 3) (Expected answer would be as; Associative Properties)
- Announce that in this lesson we will verify these properties for the multiplication of fractions.
Individual & Pair Group Task:
Sum up / Conclusion
- Recap the main points of the lesson and conclude by giving one example of each that multiplication of fractions is commutative as well as associative.
- Write following questions of fractions on the board and ask students to work in pairs, and groups.
- Select any 2 questions and verify both properties.
- Each student in pair or group must select different questions.
- Then swap their copies for peer checking.
- Ask students to work in groups and show in groups and show with examples that whether these properties are verified in division as well.
