Division 101Kristi Walker 4th Grade
Today you will need:
• Pencil• Paper• White Board• Dry Erase Marker• Multiplication Table
What are we going to learn today?
The state of Tennessee says:
SPI 406.2.1: Solve problems using whole number division with one- or two-digit divisors.
What are we going to learn today?
HUH?
What are we going to learn today?
The state of TN is using fancy words to say this…
We are going to learn how many times a one-digit number will fit into another number. This process is known as division.
When would I ever need to know that?
Tonight for dinner your Mom and Dad are goingto order a pizza for you, your little brother, and them to eat. The pizza has 8 pieces. How many pieceswould each of you get if everyone gets the same number of pieces?
Lets look at another example:I have a basket of 20 apples that I picked from my apple tree in the back yard. I would like to give 5 of my closest friends some of my apples. I want to give them all the same number of apples because I do not want to hurt any of their feelings. How many apples will each friend get?

Words To Know:
• Dividend• Divisor• Quotient• Remainder
Dividend:The number that is being divided.
Examples:3 18
18 3
Divisor:The number by which the dividend is being divided.
Examples: 3 18
18 3
Quotient:The answer to a division problem.
Examples:
18 3 6
3 186
Remainder:The number that is left over after one whole
number is divided by another.
Example: 3 206 R 2
Label this diagram:
6 549
Division Rules:
1. When you divide zero by any number other than zero the quotient will be zero.
Example: 0 ÷ 5 = 0How many cookies can 5 people have if there are zero cookies? 0 cookies divided among 5 people = 0 cookies each
Division Rules:
2. It is not possible to divide a number by zero.
Example: 5 ÷ 0 = ImpossibleHow many cookies can 0 people have if there are 5 cookies?
That is impossible to do!
Division Rules:
3. When you divide any number by 1 the quotient will always be the dividend.
Example: 8 ÷ 1 = 8I have a pie that has 8 slices. I am the only one there to eat it. How many slices could I eat? 8 slices divided among 1 person = 8 slices for me!
Division Rules:
4. When you divide any number by itself the quotient will always be 1. (Except zero!)
Example: 9 ÷ 9 = 1There are 9 people at the party. There are 9 party favors. How many party favors will each guest get?
9 favors divided among 9 people = 1 favor each
Lets Practice:
Answer these division problems on your white boards using what we have just learned about
the rules of division.1. 42 ÷ 0 = _____2. 56 ÷ 56 = _____3. 0 ÷ 31 = _____4. 15 ÷ 1 = _____
How are Division and Multiplication connected?
Think back to our original basket of apples….We decided that 5 people would each have 4 apples.

Inverse Operations
Multiplication and Division are Inverse Operations!
This means that they “un-do” each other
Quick Check…
• When you hear the Magic Word, take 30 seconds to tell your neighbor what it is that we are learning today….
Using Multiplication to Solve Division: 9 72
1. Look across the top row of your multiplication chart until you find the divisor.
2. Follow that column down until you find the dividend.
3. Follow that row to the far left to find the quotient.

Word Problem Practice:
Which operation do we use?
Medina Middle School students recently sold candy bars to raise money for the school. Each box of candy was worth $50. Mrs. Chelsea had 18 students sell a box of candy, Mrs. Carter had 14, and Mrs. Walker had 22. How much money did Mrs. Carter’s class raise?
Multiplication!

“fluff?”
Word Problem Practice:
Which operation do we use?
I have one dozen candy bars and half a dozen cookies. There are 4 students that have earned a reward for displaying good citizenship at school and 6 students who earned a reward for making an A on their math test. If I want to give all my candy bars to the students who made and “A,” how many candy bars will each one get?

Write your own word problem that requires the use of division to solve.
Swap papers with a neighbor and solve their problem.
Swap back and check their work.
Put Your Thinking Caps On…
• Can we have division without multiplication? Why or Why not?
What did we learn today?
Write it down….
We learned how to divide whole numbers that have one-digit divisors.
