They will then cut another set of numbers and place them in the cup labeled I . Each pair will cut one set of numbers and place them in the cup labeled G .

Each of these cards will be cut up and represent one group. Use beans to represent items and place them in groups. 1 Card, or 1 GROUP that has 3 Beans, or 3 ITEMS in the group.

Recording Sheet 1 G I 2 3

G_ 2 I_ 3 2 groups represented with 2 colored squares Each square (group) has 3 beans (items). 6 beans. We have a total of

Recording Sheet 1 G I 2 3 6

Recording Sheet 2 I G 2 3

Recording Sheet 2 2 groups with 3 items per group = 2 GROUPS with 3 ITEMS per group 6 items

Recording Sheet 2 I G 2 3 6 1 0

Recording Sheet 2 1 group with 0 items per group = NO BEANS! 0 items 1 GROUP with 0 ITEMS per group

Recording Sheet 2 I G 2 3 6 1 0 0

Recording Sheet 3 I G 2 3 6 = 6

Recording Sheet 4 G I 3 2

Recording Sheet 4 G I 3 6 2 = 6

First group of 3 items Second group of 3 items 2 groups of 3 items 2 3 = 6

First group of 3 items Second group of 3 items Replace the beans with SHADING! 2 groups of 3 items 2 3 = 6

2 groups of 3 items 2 3 = 6
