Why use division?
Division
is used for figuring out how many groups of the same size there
are in a set or collection of objects. Division is also
useful for finding out how many objects are in each group when
a set is divided.
Here is an example of when you might use division:
There are 21 students in your class.
Your teacher wants to create
4 groups of students. To figure out
how many students would be in each group, you need to divide.
21 students ÷ 4
groups = 5 students in each group,
with
1 student remaining

This means that when 21 is divided
into 4 groups, there are
five students in each group with a remainder
of 1 student.
or
4 divides into 21
five times with a remainder
of 1.
Vocabulary
