Today, we’re going to learn about two important math ideas: addition and subtraction. Let’s have some fun with numbers!
Addition is when we put numbers together to make a bigger number. When we add, we find something called the “sum.” It’s like when you have some toys and you get more toys. Let’s try a fun example!
If you have 3 pencils and you get 2 more pencils, how many pencils do you have now? Let’s count: 3 + 2 = 5. So, you have 5 pencils altogether!
Here’s another one: If you have 2 dogs and you get 2 more dogs, how many dogs do you have now? Let’s see: 2 + 2 = 4. Now you have 4 dogs!
Subtraction is when we take numbers away to make a smaller number. When we subtract, we find something called the “difference.” It’s like when you have some candies and you eat some. Let’s try a fun example!
If you have 4 balls and you take away 2 balls, how many balls do you have left? Let’s count: 4 – 2 = 2. So, you have 2 balls left!
Here’s another one: If you have 6 apples and you eat 3 apples, how many apples do you have left? Let’s see: 6 – 3 = 3. Now you have 3 apples!
Here’s a special rule about the number 0: When you add or subtract 0, the number stays the same. It’s like magic! So, if you have 5 toys and you add 0 toys, you still have 5 toys. And if you have 7 candies and you eat 0 candies, you still have 7 candies!
Now you know how to add and subtract! Keep practicing, and you’ll get even better at it. Math is fun!
Number Hunt: Go on a number hunt around your house or classroom! Find different objects like toys, books, or fruits. Try adding them together. For example, if you find 3 red blocks and 2 blue blocks, how many blocks do you have in total? Write down your findings and share with a friend or family member.
Subtraction Story Time: Create a short story using subtraction. For example, imagine you have 5 cookies and you give 2 to a friend. How many cookies do you have left? Draw pictures to go along with your story and share it with the class. This will help you see how subtraction works in real life!
Zero Magic Trick: Try the magic of zero with your toys or snacks. Start with a number of items, like 4 toy cars. Add 0 more cars and see how many you have. Then, take away 0 cars and check again. Discuss with a partner why the number stays the same. It’s like a magic trick you can do with numbers!
Here’s a sanitized version of the YouTube transcript:

When you add, you put numbers together. When you add, you get the sum. It’s taking two or more numbers and getting a greater one. Adding is called addition.
When you subtract, you take away. When you subtract, you get the difference. It’s taking one number from another and always getting less. Subtracting is called subtraction.
Let’s try an addition problem that you can solve. If you have 3 pencils and you add 2 more pencils, how many pencils do you have altogether? 3 + 2 = 5.
Let’s try another addition problem. If you have 2 dogs and you add 2 more dogs, how many dogs do you have altogether? 2 + 2 = 4.
Now, let’s try a subtraction problem. If you have 4 balls and you subtract 2 balls, how many balls do you have left? 4 – 2 = 2.
Let’s try another subtraction problem. If you have 6 apples and you subtract 3 apples, how many apples do you have left? 6 – 3 = 3.
Now, listen to this important rule about the number 0: When you add or subtract 0, the number doesn’t change. When you add or subtract 0, the number stays the same.
