| The
Meaning of Division (3-1) |
Draw picture to show each situation.
Then find the quotient. |
1.
Eighteen people are waiting to enter
a
store, and only 6 people are
allowed
to enter at a time. How
many
groups will need to enter? |
2.
In an animal shelter, there are 4
times
as many cats as dogs. If there
are
36 cats, how many dogs are in
the
shelter? |

Show
the picture you drew for
each problem. How does it show
the quotient? |
 |
Is the division situation
in each
problem best described as division
as
sharing, division as repeated
subtraction, or division as
a missing
factor?

| Estimating
Quotients (3-3) |
| Estimate each quotient. |
