Hello everyone! Welcome to our exciting math adventure with air balloons. Today, we’re going to learn how to add and subtract by tens using a fun worksheet called “Air Balloon Math.” Let’s get started!
Our goal is to check the air balloons with the correct math problems. We will use some cool tricks to help us solve these problems. The most important part is working with tens.
Let’s look at the first balloon. It says 17 minus 10 equals 9. Let’s see if this is true.
First, we write the equation: 17 minus 10 equals 9. To check, we can use a T-chart. A T-chart helps us see the tens and ones in a number.
For 17, we have one group of ten and seven ones. For 10, we have one group of ten and no ones. Now, let’s solve:
So, 17 minus 10 equals 7. This means the balloon is not correct because it said 9.
Now, let’s try 3 plus 10. We use the T-chart again:
This gives us 13, which matches the balloon. Yay, it’s correct!
Next, we have 14 minus 10. Let’s check:
This matches the balloon, so it’s correct!
Let’s check 10 plus 10. We can use base 10 blocks:
This is correct, so we put a checkmark!
Now, let’s see 1 plus 10. If we add:
This does not match the balloon, which said 12. So, it’s not correct.
Next, we have 16 minus 10. Let’s check:
This does not match the balloon, so it’s not correct.
Let’s try 8 plus 10. Using the T-chart:
This gives us 18, which is correct!
Finally, we have 19 minus 10. Let’s check:
This matches the balloon, so it’s correct!
You did an amazing job checking all these math problems. Keep practicing, and you’ll become a math superstar! See you next time. Bye-bye!
Balloon Number Hunt: Go on a number hunt around your home or classroom. Look for objects that come in groups of ten, like pencils, crayons, or blocks. Count them and practice adding or subtracting ten from the total. For example, if you find 20 crayons, ask yourself, “What happens if I take away 10?” or “What if I add 10 more?” Share your findings with a friend or family member.
DIY T-Chart: Create your own T-chart using paper and crayons. Write down different numbers and practice breaking them into tens and ones. Then, use your T-chart to solve addition and subtraction problems by tens. For example, write down the number 25, and then solve 25 minus 10 or 25 plus 10 using your chart. Decorate your T-chart with colorful balloons to make it fun!
Story Time with Numbers: Create a short story using numbers and balloons. Imagine you are at a balloon festival, and each balloon has a number. Write a story about how you add or subtract balloons to make new numbers. For example, “I had 15 balloons, but I gave 10 to my friend. Now I have 5 balloons left!” Share your story with the class or your family.
Sure! Here’s a sanitized version of the transcript, removing any unnecessary filler words and maintaining clarity:

Welcome to Kids Academy! Hello everyone! Let’s open the worksheet. Don’t forget to like this video and subscribe to our channel. You can find the link to this app in the comments below.
Today, we will be working on a worksheet called “Air Balloon Math.” This worksheet focuses on adding and subtracting by tens. I will show you a couple of techniques to help solve these problems. The key part is working with tens.
The directions say to add and subtract by 10 and check only the air balloons with correct equations. Let’s look at the first balloon. It says 17 minus 10 equals 9. We need to check if this is correct.
First, let’s write out the equation: 17 minus 10 equals 9. Now, we will check if this is true. Starting with 17 minus 10, we can use a T-chart to help us solve the problem.
At the top of the T-chart, we label one side for ones and the other for tens. For the number 17, we have one group of ten and seven ones. For the number 10, we have one group of ten and no ones.
Now, let’s solve the problem vertically. Starting with the ones column: 7 minus 0 equals 7. Next, we have 1 minus 1, which equals 0. So, 17 minus 10 equals 7. This does not match the original statement of 9, so we will not put a checkmark here.
Sometimes we make mistakes, so let’s check again. Another way to solve this is by using base 10 blocks. For 17, we have one group of ten and seven individual units. When we subtract 10, we cross it out and count what’s left, which is 7. Both methods confirm that the answer is 7, not 9.
Now, let’s move on to the next problem: 3 plus 10 equals 13. We can use the T-chart again. For 3, we have three units of one and for 10, we have one group of ten. Adding these together, we find that 3 plus 0 equals 3 and 1 plus 0 equals 1, giving us a total of 13. This matches the original statement, so we will put a checkmark here.
Next, we have 14 minus 10 equals 4. Writing it out, we see that 14 has one group of ten and four units of one. Subtracting 10 leaves us with four, which matches the original statement. So we will put a checkmark here.
Now, let’s check 10 plus 10 equals 20. We can do this with base 10 blocks. Adding two groups of ten gives us 20, which is correct. We will put a checkmark here.
Next, we have 1 plus 10 equals 12. If we think about it, 1 plus 10 equals 11, not 12. So we will not put a checkmark here.
Now, let’s check 16 minus 10 equals 5. Writing it out, we find that 16 has one group of ten and six units of one. Subtracting 10 leaves us with six, which does not match the original statement. So we will not put a checkmark here.
Next, we have 8 plus 10 equals 18. Using the T-chart, we find that 8 plus 0 equals 8 and 1 plus 0 equals 1, giving us 18. This is correct, so we will put a checkmark here.
Finally, we have 19 minus 10 equals 9. Writing it out, we see that 19 has one group of ten and nine units of one. Subtracting 10 leaves us with nine, which matches the original statement. So we will put a checkmark here.
Great job today! You checked all of these math problems and confirmed which ones were correct. I’m proud of you! I will see you again next time. Bye-bye!
