Hey there! Guess what? I’m so excited because I’m having a birthday party on Friday! I need to figure out how many friends are coming so I can send out invitations. Let’s do some math to find out!
First, I want to invite my friends from two different classes. I have nine friends in my first class and eight friends in my second class. Let’s add them up to see how many invitations I need to send.
To find out the total number of friends, we add nine plus eight. Let’s do the math:
9 + 8 = 17
So, I need to send out 17 invitations because 17 friends are coming to my party!
Oh no! Ellie and Little Blue told me they can’t make it to the party. Let’s see how many friends will still be coming.
We invited 17 friends, but 2 can’t come. Let’s subtract to find out how many friends will be there:
17 – 2 = 15
That means 15 friends will be joining the fun at my party!
We’re going to have a fantastic time at the party with all our friends! If you enjoyed learning with me, you can find more fun videos on the Smile Alert channel. Just click on the circle with a seal to subscribe and get new videos every week. Keep learning and having fun!
Invitation Count Game: Pretend you are planning your own party! Use small objects like buttons or coins to represent your friends. First, count how many friends you want to invite from your class and place that number of objects in one group. Then, count how many friends you want to invite from your neighborhood and place those objects in another group. Add the two groups together to find out how many total friends you will invite. Can you write down the addition sentence for your party?
Subtraction Story Time: Create a story about a party where some friends can’t come. Use toys or drawings to show your friends at the party. Then, choose a few toys or drawings to “leave” the party. Count how many friends are left and write down the subtraction sentence. Share your story with a family member or friend!
Everyday Math Detective: Be a math detective at home! Look around your house and find things you can add or subtract. For example, count how many apples are in the fruit bowl, then subtract how many you eat. Or, add the number of chairs in the kitchen to the number of chairs in the living room. Write down your math sentences and share them with your class.

[Music] Oh, I can’t wait for Friday! Did you know that we’re going to have my birthday party then? Yes! How many people are coming? Have you given out invitations yet? No, I have to count how many friends are going to be there. Oh, I have class; I don’t want to be late. We will talk later.
So, how many friends are going to the party? How many invitations do you have to send? How many friends do I need to send party invitations to if I want to invite nine classmates from my first class and eight classmates from my second class?
[Music]
To know how many invitations I need, I have to add up the number of friends I want to invite. From my first class, I am going to invite nine people, and from my second class, I’m going to invite eight people. Let’s add.
We’re going to add: if we have nine friends in the first class and eight friends in the second class, nine plus eight is seventeen. Let’s put seven here in the units column and the one in the tens column. Great! There are seventeen, so 17 friends are coming. Ellie and Little Blue told me they can’t come, so how many are going?
[Music]
To know how many friends are going to come, we have to subtract. I invited 17 friends, but 2 can’t come. 17 minus 2 is 15. Let’s put the 5 in the units column and the one in the tens column like this. Now we have the total of friends going to the party.
