Dividing: Grouping vs. Sharing CCSS.6.NS.1: Apply and extend previous understandings multiplication and division to divide fractions by fractions. You need your Journal, a pencil, and a ruler. You will get a new assigned seat today. Be prepared to move.

2
Set up your Journal as shown: Grouping ProblemsSharing Problems 12 ÷ 3 = 4 10 ÷ 5 = 2

3
Grouping Problem: Act it Out If there are 3 people on each team, how many teams can you make with 12 people?

4
Grouping Problem: Act it Out If there are 3 people on each team, how many teams can you make with 12 people? So, 12 people ÷ 3 people = 4 teams Draw a picture model on the worksheet in your Journal of this situation.

5
Grouping Problem: Act it Out If there are 3 people on each team, how many teams can you make with 12 people?

6
Grouping Problem: Use the colored disks to model this problem. If there are 5 sandwiches on each platter, how many platters do you need to feed 10 people? Draw a picture model in your journal of this situation.

7
Grouping Problem: Use the colored disks to model this problem. If there are 5 sandwiches on each tray, how many trays do you need to feed 10 people? Draw a picture model in your journal of this situation. 10 sandwiches ÷ 5 sandwiches = 2 trays

8
Sharing Problem: Act it Out If there are 12 people on 3 teams, how many people are on each team?

9
Sharing Problem: Act it Out If there are 12 people on 3 teams, how many people are on each team?

10
Sharing Problem: Act it Out If there are 12 people on 3 teams, how many people are on each team? So, 12 people ÷ 3 teams = 4 people/team How does this compare/differ from the grouping problem, 12 ÷ 3 = 4?

11
Sharing Problem: Use the colored disks to model this problem. If there are 10 sandwiches on 5 trays how many sandwiches on each tray? Draw a picture model in your journal of this situation. How does this model compare/differ from the grouping model?

12
Sharing Problem: Use the colored disks to model this problem.

13
If there are 10 sandwiches on 5 trays how many sandwiches on each tray? Draw a picture model in your journal of this situation. So, 10 sandwiches ÷ 5 trays = 2 sandwiches/tray How does this model compare/differ from the grouping model?

14
Review Review models using the manipulatives (color discs). Which is Grouping? Sharing? If there are 28 marbles in 4 bags, how many marbles in each bag? (28 marbles ÷ 4 bags = 7 marbles per bag) If there are 4 marbles in each bag, how many bags can you use with a total of 28 marbles? (28 marbles ÷ 4 marbles per bag = 7 bags) Discuss the differences in what the question is asking as to how students will divide the discs.

15
Practice Use the same ideas of grouping and sharing to create bar models and number lines for the same 2 problems.
