4. What is Division? Dividend ÷ Divisor = Quotient
Division can be defined as “ A part or whole being shared equally”. Notice that the Dividend always comes first in the equation and refers to what is being shared. Also, notice that the second part of the equation directly behind the division symbol is called the Divisor. Depending on the type of question , you are answering the divisor can describe 2 different things based on 2 different models called Partitive and Measurement . The answer to a division problem what’s called a quotient . The Quotient or answer to a division number sentence can also describe 2 different things based on the Partitive and Measurement model. It is important to know what each part of a division equation represents and to place each part in the correct order when setting up an equation to get the correct quotient.
Quick tips to remember
Quotient × Divisor= Dividend
Quotient ÷ Dividend = Divisor
Quotient ÷ Divisor= Dividend
Try applying it using some real world whole numbers.!

5. Partitive Model
Partitive Model’s Divisor The divisor describes how many ( people, rooms, groups, etc. ) are sharing something. Example 6 ÷2 = 3 The divisor 2 could possibly be describing 6 books shared equally by 2 people, or 2 classrooms or, or 2 groups of students.
Partitive Model’s Quotient The quotient describes How much of the whole or part being shared (Dividend) each group or person will receive. So if 6 books are shared equally by 2 groups, then each group will receive 3 books.

6. Measurement Model Measure Model’s Divisor Measure Model’s Quotient
. Divisor often describes the size of each piece that will be equally shared.
Example
6 ÷ = 18
The divisor could possibly describing a 6 foot log being equally cut into smaller logs that are each 𝟏 𝟑 of a foot.
Quotient describes “how many groups can be made out of what is being shared?”
So, if a 6 foot log Is equally chopped into smaller logs that 1/3 of a feet each. 18 smaller logs can be made from the 6 foot log .
1/3 is a unit fraction because it has a numerator of 1.

7. The Division symbol ÷/ 𝑛 𝑑
The division symbol can be used to represent a fraction. The fraction symbol can be used to represent a division expression.
More Examples
3 friends share 5 candy bars.
5 ÷3= * The candy bars are being shared ( Dividend) so must come first in the expression. So each friend will receive or pieces of the candy bar.
Example The Expression 5 ÷2 can be written as 5 2 Remember the operation of Division is not Commutative, therefore, order matters. So, the Expression 2÷𝟓 can be expressed as 𝟐 𝟓 .
