Presentation Transcript

Slide1

Equal Sharing & Equal GroupingSlide2

Get with your partner and take turns taking one or two counters from the pile of 18.

How many counters do you each have?

You should each have 9 counters.

What multiplication fact can we make from this?

2 x n = 18

n

= 9Slide3

In this example, you knew:

The total number of counters.

The number of groups.

This is called

Equal Sharing

.Slide4

You and your partner count out 16 counters. Set the other remaining counters to the side.

How many groups are there?

You should each have 4 groups.

What multiplication fact can we make from this?

n

x 4 = 16

n

= 4

Count out 4 counters per group.Slide5

In this example, you knew:

The total number of counters.

The number counters in each group.

This is called

Equal Grouping

.Slide6

Equal _____________: Total number of objects and number of groups are known, but number of objects in each group is unknown.

Sharing

Equal _____________

: Total number of objects and number of objects in each group are known, but number of groups is unknown.

GroupingSlide7

1. ______ x 3 = 21

 

 

   

  Did you do equal sharing or equal grouping?Slide8

“I Can” Statement:

I can tell the difference between equal sharing and equal grouping and apply it to multiplication facts.
