Understand Division
As in the cases of addition and multiplication, certain properties hold for division. The Property of One for Multiplication
(also called the Identity Property of Multiplication) states that for any number n, n × 1 = n. This property is applied to
division in the following forms.
For any number n, n ÷ 1 = n.
For any number n, n ≠ 0, n ÷ n = 1.
The Zero Property of Multiplication states that for any number n, n × 0 = 0. Because multiplication and division are inverse
operations, the statement implies that
For any number n, n ≠ 0, 0 ÷ n = 0.
The condition n ≠ 0 is essential in the above statements because neither n ÷ 0 nor 0 ÷ 0 are defined.
Division With Remainders
When you divide a group of objects into smaller equal groups, there may be some objects left over. For instance, when
you divide 18 by 7, the result is seven groups of 2 with 4 left over. The 4 left over is the remainder in the division problem.
The answer to the division in the example is usually written 2 R4. When the result of the division is checked using
multiplication, the remainder must be added to the product of the divisor and the quotient. The resulting sum should equal
the dividend in the original problem.
Understand Fractions
Fractions
Fractions are numbers that are needed to solve certain kinds of division problems. Much as the subtraction problem
3 − 5 = −2
creates a need for numbers that are not positive, certain division problems create a need for numbers that are not
integers. For example, fractions allow the solution to 17 ÷ 3 to be written as
17 ÷ 3 = .
When a and b are integers and b ≠ 0, then the solution to the division problem a ÷ b can be expressed as a fraction, .
Page 4 of 40
At this grade level, students should learn to identify fractions with models that convey their properties. Proper fractions
can be modeled in terms of a part of a whole. The whole may be a group consisting of n objects where part of the group
consists of k objects and k < n. The fraction can be modeled as follows.
Equivalently, the whole may consist of a region that is divided into n congruent parts, k of which belong to a subregion.
For example, the fraction can be identified as the shaded part of the region below.
A unit fraction is a fraction with a numerator of 1 (for example, , , , ). The definition of a unit fraction, , is to take one
unit and divide it into n equal parts. One of these smaller parts is the amount represented by the unit fraction. On the
number line, the unit fraction represents the length of a segment when a unit interval on the number line is divided into n
equal segments. The point located to the right of 0 on the number line at a distance from 0 will be .
The fraction can represent the quotient of m and n, or m ÷ n. If the fraction is defined in terms of the unit fraction ,
the fraction means m unit fractions . In terms of distance along the number line, the fraction means the length of m
abutting segments each of length . The point is located to the right of 0 at a distance m × from 0. The numerator of
the fraction tells how many segments. The denominator tells the size of each segment.
A straightforward way to show that fractions represent a solution to a division problem is by using equivalent fractions.
What is 35 ÷ 7? It is 5 because 35 equals 7 × 5. What is 5 ÷ 7? This is more difficult because 5 is not a multiple of 7.
However, 5 = = 5 × × 7 = , and equals 35 unit fractions of . Just as 35 divided by 7 is 5, 35 unit fractions of
divided by 7 is 5 unit fractions of . So 5 ÷ 7 = .
Finding a Fractional Part of a Number
The word of is often used to pose problems involving the multiplication of a whole number by a fraction. At this level,
students have not yet learned to multiply fractions. The problem of finding of 6 can be modeled in terms of a group of 6
objects that has been separated into 3 smaller groups, each of which has 2 objects.
Page 5 of 40
Equivalent Fractions
Two fractions and are equivalent if there exists a number m such that m × × b = . For example, the fact that 2 ×
× 4 = implies that is equivalent to .
Geometrically, this concept can be conveyed in terms of a picture in which there are two ways of representing the same
part of the whole. The fact that is equivalent to can be shown as follows.
Because equivalent fractions represent the same number, they are referred to as equal.
A fraction is in simplest form if the numerators and denominators are as small as possible. A more formal way of stating
this is to say that in a simplest form fraction, the numerator and denominator have no common factors other than 1.

Teaching Tips
Fractions TeachingTip1
Focus on the understanding of fractions and fraction models to represent the addition and subtraction of fractions with unlike denominators as equivalent calculations with like denominators. Develop fluency in calculating sums and differences of fractions, and make reasonable estimates of them. Also, use the meaning of fractions, of multiplication and division, and the relationship between multiplication and division to understand and explain why the procedures for multiplying and dividing fractions make sense. (Note: this is limited to the case of dividing unit fractions by whole numbers and whole numbers by unit fractions.)
Division TeachingTip2
Develop understanding of why division procedures work based on the meaning of base-ten numerals and properties of operations. Students use the relationship between decimals and fractions, as well as the relationship between finite decimals and whole numbers (i.e., a finite decimal multiplied by an appropriate power of 10 is a whole number), to understand and explain why the procedures for multiplying and dividing finite decimals make sense. They compute products and quotients of decimals to hundredths efficiently and accurately.
What do I Focus On? TeachingTip3
Instructional time should focus on three critical areas: (1) developing fluency with addition and subtraction of fractions, and developing understanding of the multiplication of fractions and of division of fractions in limited cases (unit fractions divided by whole numbers and whole numbers divided by unit fractions); (2) extending division to 2-digit divisors, integrating decimal fractions into the place value system and developing understanding of operations with decimals to hundredths, and developing fluency with whole number and decimal operations; and (3) developing understanding of volume.

Camping Trip
One week from today we will be at Stokes State Park in Branchville, New Jersey! We are going to be staying
in the cabins near Lake Ocquittunk. Before we go, we need to decide on cabin arrangements. Attached to
this page you will find a map of the Lake Ocquittunk camping area. There are three classes going on the trip,
Mr. Viater’s class of 23 students, Ms. Elliott’s class of 29 students, and Mrs. Ambolt’s class of 28 students.
In addition to the three teachers, there will also be a total of 20 adult chaperones on the trip.
Your job is to figure out what the sleeping arrangements should be. We have reserved all of the cabins and
each one can have a maximum of 8 people in it. Prove what you think would be the best arrangement.
How many people should be in each cabin? Is there more than one way to solve this? What things do you
need to think about before you start solving the problem? How did you solve this? Make sure you explain
your results using as much math language as possible and include some form of representation as well.
Good luck, and remember... show all your work!

3 This student shows a deep understanding of the problem. S/he takes into
account the number of students from each classroom and the number of
chaperones. S/he made the number of students in each cabin as equitable
as possible. This student explains how s/he got his/her answers and uses
appropriate representation.
2 The student's response shows that s/he has a broad understanding of the
problem and the major concepts. His/her reasoning is effective and s/he
proceeds appropriately. His/her work is efficient and clear. However, this
student does struggles with the concept of dividing the students and
chaperones evenly among the cabins.
