Carla wants to share her cookies with her
mother. She puts her cookies into two groups,
one for herself and one for her mother.
How many cookies will each of them get?
9
Do you think Carla and her mother each will get
FIFTEEN cookies? TEN cookies? FIVE cookies?
10
If you guessed that Carla and her mother will get
TEN cookies each, youre correct!

Lets see how to figure this out.

The problem is 20 2. First, lets see
what the problem means Carla has 20 cookies
and puts them into two groups. How many will
be in each group?
Next we will make two groups.
Then begin adding one cookie to each group until
you have used all of the
cookies.

Mother
12
There are ten cookies in each group so Carla
and her mother will get ten cookies.
How do you think youll write the complete
division problem?

one for everyone present.
