Session 5 - Division of Fractions

Collaborative Activity #2 (15 minutes)

Activity: Collaborative Activity #2

Directions: 

1. Hand out Collaborative Activity #2
2. Working independently or in groups, have students review the handwritten answers on the division of fractions worksheet.
3. Students should work in their groups (or individually at first then in groups) to discuss which of the answers are correct and incorrect, and why. You may choose to create a poster for these and the students can do a gallery walk (see the Resource Bank for information on conducting a gallery walk).

Answers:

1.  a. Correct
2. b. Incorrect. The student is dividing by whichever value is larger
3. c. Incorrect. The student is not multiplying by reciprocal
4. d. Correct. However, the student finds a common denominator and then uses the algorithm for the division of fractions. This makes the multiplication problem harder and is not needed.
5. e. Incorrect. The student correctly followed the algorithm for multiplication but then performed “cross multiplication”
6. f. Correct
