**Division**
**There are four basic operations
in mathematics:**

**These operations define
***actions*. They are not static statements, but dynamic
interactions between quantities.

**Division****
is the action of ***seperating* quantities into groups of a given
size (grouping), or a certain number of groups (sharing). It can also
be modeled with an area model. Let's look at 18 ÷ 6 = 3. Here is
an example of the grouping model:

**Here's a look at a sharing
model:**

**In the area / rectangle
model, the first number in the division problem (the dividend) is
the area of the rectangle, and the second number (the divisor) is
one of the dimensions. The answer (the quotient) is the other
dimension. Here's how that looks:**

**The models are simple, yet
powerful. They will work for operations with fractions, decimals, and
signed numbers, as well as algebraic operations. We'll learn more
about those in future lessons.**
