Math worksheets and visual curriculum Subtraction helps us to find the difference. Subtraction can tell us how many are left. Subtraction is easy to do! Subtraction is the opposite of addition. We can use subtraction in word, or story, problems. Subtraction skills can help us solve correctly! For example: Let's take a look at the example above. We are subtracting because some of the dolphins swim away. There are 10 dolphins to start with and 5 swim away. We need to figure out how many are left. We can do this by subtracting 10 ? 5 to get our answer. We write it like this: 10 ? 5 = 5 There are 5 dolphins left! Let's look at another problem! Let's take a look at the example above. We are subtracting because some of the butterflies fly away. There are 11 butterflies to start with and 4 fly away. We need to figure out how many are left. We can do this by subtracting 11 ? 4 to get our answer. We write it like this: 11 ? 4 = 7 There are 7 butterflies left! Amazing work! Let's look at another problem together. This time we will subtract strawberries. We are SUBTRACTING to find out how many are left because some have been eaten. We can see that there were nine strawberries to start with. Six of them have been eaten When we SUBTRACT 9 minus 6, we have 3 left. We say: NINE minus SIX equals THREE. We write it like this: 9 ? 6 = 3 Let's try one more together! This time we will subtract donuts. We are SUBTRACTING to find out how many are left because some have been eaten. We can see that there were ten donuts to start with. Six of them have been eaten When we SUBTRACT 10 minus 6, we have 4 left. We say: TEN minus SIX equals FOUR. We write it like this: 10 ? 6 = 4 There are many different words that are used to describe subtraction. For example, we can find out HOW MANY MORE there are or how many ARE LEFT. Here are several other examples: Knowing these keywords will help you understand that in order to solve some problems, you must subtract. You might see these keywords in math story problems. There are many strategies you can use to help you subtract correctly. We will learn about these in other lessons. Now, let's practice! Page 2 We can use math to solve problems! Sometimes, we want to know how many there are in all, so we add. Sometimes, we want to know the difference between two groups, so we subtract! You can find how many are left by using subtraction. Subtraction is the action of separating two groups. Let's take a closer look at the example above. There are five balloons, but two of the balloons are crossed out. We can SUBTRACT to find the difference between the two groups. We started with FIVE balloons, but TWO of the balloons are gone. When we SUBTRACT 5 minus 2, we have 3 left. We say: FIVE minus TWO equals THREE. We can write it like this: 5 ? 2 = 3 Here's another example. In this problem, we are finding the difference between two groups of cookies. We are SUBTRACTING to find out how many are left. This will tell us how many cookies are left. We can see that there were eight cookies to start with. Four of the cookies are now gone. When we SUBTRACT 8 minus 4, we have 4 left. We say: EIGHT minus FOUR equals FOUR. We write it like this: 8 ? 4 = 4 Here is another one to try. In this problem, we are finding the difference between two groups of seashells. We are SUBTRACTING to find out how many are left. This will tell us how many seashells are left. We can see that there were six seashells to start with. Three of the seashells are now gone. When we SUBTRACT 6 minus 3, we have 3 left. We say: SIX minus THREE equals THREE. We write it like this: 6 ? 3 = 3 Let's try one more! This time, we are subtracting the number 7 from the number 9. The first number in the subtraction sentence is called the MINUEND. The second number in the subtraction sentence is called the SUBTRAHEND. This problem reads as 9 ? 7 = 2. When the SUBTRAHEND 7 is subtracted from the MINUEND 9, we get a DIFFERENCE of 2. DIFFERENCE is used to describe the amount that is left. There are many different words that are used to describe subtraction. For example, we can TAKE AWAY a number to find the DIFFERENCE. Here are several other examples which you should be familiar with: Knowing these keywords will help you understand that in order to solve some problems, you must subtract. Let's try introducing subtraction in basic word problems. In the problem, Bert has more cars than Bob. The key word is DIFFERENCE. This helps tell us that we need to SUBTRACT. Bob has 8 cars. Bert only has 4 cars. We can subtract to find the DIFFERENCE. 8 ? 4 = 4 cars There are many strategies you can use to help you subtract correctly. We will learn about these in other lessons. Now, let's practice! Page 3 We can use subtraction to find the difference between a big group and a small group. Subtraction can tell us how many are left. Subtraction helps us to separate two groups and find the difference! Many times we have a group of objects and we want to take one away from the group. For example: There are 3 cats, but 1 cat is crossed out. We can SUBTRACT to find out how many ARE LEFT. This will give us the DIFFERENCE. When we SUBTRACT 3 minus 1, we have 2 LEFT. We say: THREE minus ONE equals TWO. We write it like this: 3 ? 1 = 2 Let's look at another problem! There are 6 trucks, but 1 truck is crossed out. We can SUBTRACT to find out how many ARE LEFT. This will give us the DIFFERENCE. When we SUBTRACT 6 minus 1, we have 5 LEFT. We say: SIX minus ONE equals FIVE. We write it like this: 6 ? 1 = 5 Simple! Let's look at another problem together. This time we will subtract smiley faces. We are SUBTRACTING to find out how many are left. We can see that there were four smiley faces to start with. One of the smiley faces is now gone. When we SUBTRACT 4 minus 1, we have 3 left. We say: FOUR minus ONE equals THREE. We write it like this: 4 ? 1 = 3 Are you ready to try another problem that involves subtracting by 1? In this example, we are subtracting the number 1 from the number 8. The first number in the subtraction sentence is called the MINUEND. The second number in the subtraction sentence is called the SUBTRAHEND. This problem reads as 8 ? 1 = 7. When the SUBTRAHEND 1 is subtracted from the MINUEND 8, we get a DIFFERENCE of 7. When we want to find what ONE LESS is in a group of objects, we can remember that the DIFFERENCE will be the number that comes BEFORE when we are counting. 5 ? 1 = For example, 5 ? 1 = 4. We also know that when we count, the number that comes before 5 is the number 4. This can help us to subtract quickly and correctly when subtracting 1 from a group. Here is another example. When we want to find what ONE LESS is in a group of objects, we can remember that the DIFFERENCE will be the number that comes BEFORE when we are counting. 11 ? 1 = For example, 11 ? 1 = 10. We also know that when we count, the number that comes before 11 is the number 10. This can help us to subtract quickly and correctly when subtracting 1 from a group. You're doing an amazing job! Now, let's go ahead and review some key words that relate to subtraction. When you see these words in a problem, they should hint to you that subtraction is involved. Writing down these keywords above is a great way to remember these important words! Here's a word problem dealing with "Subtracting by 1". In the problem, we start with 9 bananas. The key words ARE LEFT tell us to subtract. ONE banana is eaten from the group. We can subtract to find the DIFFERENCE. 9 ? 1 = 8 bananas Now, let's practice! Page 4 Previously, you have learned how to subtract by 1, 2, and 5. Today, we are going to learn and work with problems dealing with subtracting by 10! Let's dive right in and take a look at an actual practice problem. There are 13 fish, but 10 fish are crossed out. We can SUBTRACT to find out how many ARE LEFT. This will give us the DIFFERENCE. When we SUBTRACT 13 minus 10, we have 3 LEFT. We say: THIRTEEN minus TEN equals THREE. We write it like this: 13 ? 10 = 3 Let's look at another problem! In this example, there are 17 trains, but 10 trains are crossed out. We can SUBTRACT to find out how many ARE LEFT. This will give us the DIFFERENCE. When we SUBTRACT 17 minus 10, we have 7 LEFT. We say: SEVENTEEN minus TEN equals SEVEN. We write it like this: 17 ? 10 = 7 Awesome! We will try another problem with pictures now. Let's subtract the diamonds. We are SUBTRACTING to find out how many are left. We can see that there were sixteen diamonds to start with. Ten of the diamonds are now gone. When we SUBTRACT 16 minus 10, we have 6 left. We say: SIXTEEN minus TEN equals SIX. We write it like this: 16 ? 10 = 6 Ready to try another one? We are subtracting the number 10 from the number 19. The first number in the subtraction sentence is called the MINUEND. The second number in the subtraction sentence is called the SUBTRAHEND. This problem reads as 19 ? 10 = 9. When the SUBTRAHEND 10 is subtracted from the MINUEND 19, we get a DIFFERENCE of 9. DIFFERENCE is used to describe the amount that is left. When we want to find what TEN LESS is in a group of objects, we can remember that the DIFFERENCE will be the number that comes TEN BEFORE it when we are counting. 12 ? 10 = For example, 12 ? 10 = 2. We also know that when we count, ten numbers that come before 12 is the number 2. This can help us to subtract quickly and correctly when subtracting 10 from a group. Here is another example. 13 ? 10 = For example, 13 ? 10 = 3. We also know that when we count, the number that comes ten before 13 is the number 3. This can help us to subtract quickly and correctly when subtracting 10 from a group. There are many different words that are used to describe subtraction. Take a look at the image below that shows you important words you should be familiar with. Knowing these keywords will help you understand that in order to solve some problems, you must subtract. Let's try a word problem. In the problem, we start with 19 strawberries. The key words ARE LEFT tell us to subtract. TEN strawberries are eaten from the group. We can subtract to find the DIFFERENCE. 19 ? 10 = 9 strawberries Let's get our game face on and tackle these next 5 practice questions that you should try on your own!
