Basics on the topic Making Change
Making Change
Sometimes when people are paying for items they do not have the exact amounts of money. When this happens, they pay more than they need to and receive change in return.
Money and making change is how many dollar bills or coins you get back when you pay too much. Change can be dollar bills or coins! It’s the difference of the money you pay with and how much the item costs.
How to Make Change
There are different ways that you can figure out how to make change with money. In this video we used a number line while counting money and making change. We can learn about making change by counting up! When using a number line to subtract money, you can follow these steps:
Step #  What to do 

1  Start by creating an equation. You can subtract the amount of money the item cost from how much money was given to pay for it. 
2  Next, put the larger number on the right side of the number line. 
3  Skip count backwards. 
4  Finally, the number you land on is the answer, or the change! 
Making Change with Money – Example
Let’s practice making change with the example below.
Let's imagine we are buying a lot of supplies. If we pay one hundred dollars, and the supplies cost eightythree dollars, how much change will we receive?
Let's start by setting up the equation! We know that we pay using $100 and we also know that the supplies cost $83. So in order to find out the change that remains, we set up a subtraction – 100  83. Now, let's solve our subtraction equation by taking steps back on the number line.
If we subtract 80 from 100, we can take steps of 20 on our number line. We need to take 4 of these steps with steps of 20. So, subtracting 80 from 100, we land on 20 What remains is 3. So we need to subtract 3 from 20 to get to our result.
We will receive 17 dollars back in change!
Making Change – More Practice
Remember, making change is the difference of how much you pay and how much the item costs. You can use many different tools to solve making change, such as a number line!
When using a number line to make change remember these steps:

At the end of this making change video, there are interactive exercises for continued practice of making change through counting money and making change worksheets.
Transcript Making Change
Zuri and Freddie are going on a camping trip, but, need to get some supplies first. While shopping, they might need to make change. : "Making Change" Many people often do not have exact amounts of money when paying. When this happens they receive change. Change can refer to coins and dollar bills. Making change is how many coins and dollar bills you get back when you pay too much. So, it is the DIFFERENCE of the money you PAY with and the cost of the item. In this video we will use a number line to help us subtract to find the difference. Zuri and Freddie need to buy a tent first. The tent that they want costs twentysix dollars. Freddie and Zuri give the cashier thirty dollars, how much change will they get back? We can start by subtracting the amount their tent cost from how much money they gave the cashier. The first step is to create an equation for what we need to solve. Freddie and Zuri gave the cashier thirty dollars for the twentysix dollar tent. So, we'll subtract thirty minus twentysix to create our equation. Next, we can put the larger number on the RIGHT side and skipcount back the value of the second number. We'll put thirty on the right side and count back twentysix. Then, we can skipcount backward by tens twice. After that, we count back by ones (...) six times. Finally, the number that we land on is how much change we will receive. We skipcounted backward and landed on the number four. Zuri and Freddie will receive four dollars in change. Next they are planning to buy A LOT of marshmallows. They grab fortyfive dollars worth of marshmallows. If Zuri and Freddie give the cashier sixty dollars, how much change will they receive? First we need to create an equation, how can we set it up? We can set it up as sixty minus fortyfive, since Zuri gave sixty and the price is fortyfive. Next, we can put the larger number on the RIGHT side and skipcount backward the value of the second number. We need to skip count backward fortyfive. There are different ways to skipcount backward. To create the least amount of jumps here, we can skipcount backward FOUR tens and ONE five. If we skipcount backward four tens and one five, what number will we land on? (...) We land on the number fifteen. Zuri and Freddie will receive fifteen dollars back. They also need to buy graham crackers and chocolate! They decide to buy eightythree dollars worth of the other s'mores supplies. If Zuri and Freddie give the cashier one hundred dollars, how much change will they receive back? Remember, start by creating an equation, what equation did you create? (...) We can create the equation one hundred dollars minus eightythree. Next, put the larger number on the RIGHT side of the number line. Then, skipcount backward the value of the second number. If we skipcount backward eightythree, what number will we land on? We land on the number seventeen. Zuri and Freddie received seventeen dollars back. Now Zuri and Freddie need flashlights! They decide to get color changing flashlights that cost one hundred twentytwo dollars. If Zuri gives the cashier one hundred fifty dollars, how much will she receive back? Zuri will get twentyeight dollars back. Let's summarize. Remember when making change... Start by creating an equation. Next, put the larger number on the RIGHT side of the number line. Then, skipcount backward the amount of the second number. Finally, the number that we land on is how much change we will receive back. Let's check in with Zuri and Freddie. : "Do you have my pillow?" : "I thought you packed the pillows..." : "We can just use the extra jumbo marshmallows!"
