Hey there! We are getting ready for an exciting end-of-year party, and guess what? It’s our job to organize it this time! One of the first things we need to do is send out invitations to all the students in the fourth-grade classes. Let’s figure out how many invitations we need to send.
There are three classes: 4A, 4B, and 4C. In class 4A, there are 25 students. Class 4B has 24 students, and class 4C has 27 students. To find out how many students are in all three classes, we need to add these numbers together.
Let’s start by adding the numbers in the units column. First, we add 5 (from 4A) and 4 (from 4B), which equals 9. Then, we add 9 and 7 (from 4C), which gives us 16. We write down the 6 and carry over the 1 to the tens column.
Next, we add the numbers in the tens column. Don’t forget the 1 we carried over! We add 1, 2 (from 4A), 2 (from 4B), and 2 (from 4C), which equals 7. So, there are 76 students in total. That’s how many invitations we need to send!
We already know that 11 students can’t make it to the party. So, how many students will be there? We need to subtract to find out.
Let’s subtract 11 from 76. Starting with the units column, we subtract 1 from 6, which is 5. Then, we move to the tens column and subtract 1 from 7, which is 6. So, 65 students will be coming to the party!
With 65 students coming, we’re going to have an amazing time at the party! Remember, math can help us solve real-life problems, like planning a party. Keep practicing your addition and subtraction skills, and you’ll be a math whiz in no time!
Invitation Count Challenge: At home, gather some small objects like buttons or coins. Pretend each object is an invitation. Count out 25 objects for class 4A, 24 for class 4B, and 27 for class 4C. Now, combine all the objects to find the total number of invitations needed. Can you do it without writing anything down? Try to explain your process to a family member or friend.
Subtraction Story Time: Create a short story about a party where some guests can’t attend. Use toys or drawings to represent the 76 students invited and then remove 11 to show how many will actually attend. Share your story with someone at home, explaining how subtraction helped you find out who could come to the party.
Math Detective: Next time you go to the grocery store with an adult, look at the prices of two or three items. Try adding them together in your head to find the total cost. If you have a calculator or a phone, check your answer to see if you were right. This will help you practice addition in a real-world setting!

[Music] I’m so excited for the end-of-year party! Did you know this year it’s up to us to organize it? Yes, we have to send the invitations. I already have the lists of the students from the fourth-grade classes. We need to determine how many invitations we’re going to send.
How many kids are there in each class? [Music] How many invitations do we need to send? If there are 25 students in 4A, 24 in 4B, and 27 in 4C, we need to figure out the total number of students in the three classes by adding the numbers together.
In 4A, there are 25 students, in 4B there are 24 students, and in 4C there are 27 students. Let’s look at the total. [Music]
First, we add the numbers in the units column: five plus four is nine, and nine plus seven is sixteen. We write down the six and carry over the one to the tens column. Now we add the tens column. [Music]
Don’t forget about the one we carried over. Let’s see: one plus two is three, three plus two is five, and five plus two is seven. Great! We will write the number here in the tens column. Now I’ve got it: there are 76 students in total. I will send the invitations this afternoon.
We have already received responses from our classmates: eleven aren’t coming. If there are 76 kids in the fourth-grade classes and 11 aren’t coming, how many kids are coming in total? [Music]
To find out how many students aren’t coming, we need to subtract. Starting with the units column: six minus one is five, so we put the five in the units column. Now we move to the tens column and subtract seven minus one, which is six. Let’s put that here. Done!
Now we have the total number of students who are coming to the end-of-year party: 65. We are going to have such a great time!
