ClassX Video Lessons Youtube Channel Preschool Prep Company Meet the Math Facts Addition & Subtraction Level 2 – Director Drills
Hey there! Are you ready to have some fun with math? Today, we’re going to learn how addition and subtraction are like best friends. Let’s get started!
Did you know that when you learn addition, it can help you with subtraction too? It’s true! Let’s see how it works.
Imagine you have a big number. Let’s say it’s 10. If you know that 6 plus 4 equals 10, then you can also figure out that 10 minus 6 equals 4. See how they are connected? And guess what? 10 minus 4 equals 6 too!
Now, let’s play with some more numbers. How about 11, 8, and 3? If you know that 8 plus 3 equals 11, then you can easily find out that 11 minus 8 equals 3. And don’t forget, 11 minus 3 equals 8!
Let’s practice a bit more. If 8 plus 4 equals 12, then 12 minus 8 equals 4. And of course, 12 minus 4 equals 8. You’re doing great!
Here’s another one: 1 plus 9 equals 10. So, 10 minus 9 equals 1, and 10 minus 1 equals 9. Easy peasy!
Let’s try some quick ones:
Wow, you’re a math superstar! Keep practicing, and you’ll get even better. Remember, addition and subtraction are like a team, and they always help each other out.
Have fun with your math adventures!
Number Detective: Become a number detective and find pairs of numbers around your home that add up to 10. For example, you might find 6 apples and 4 oranges in the fruit bowl. Write down your findings and then use subtraction to check your work. If you have 10 fruits and take away 6 apples, how many oranges are left?
Math Story Time: Create a short story using your toys or stuffed animals. For example, if you have 10 toy cars, make a story about how 4 cars went on a trip, and figure out how many stayed at home. Then, switch it up and have 6 cars go on a trip. How many are left at home now? Share your story with a friend or family member!
Nature Numbers: Go on a nature walk and collect small items like leaves or stones. Use these items to practice addition and subtraction. For instance, if you collect 8 leaves and find 3 more, how many do you have in total? If you give 4 leaves to a friend, how many do you have left? Try to find different combinations and share your discoveries with your class!
Sure! Here’s a sanitized version of the transcript:

Now that you’ve learned the math facts, did you know you can use them for subtraction? It’s easy! I’ll show you how.
With the largest number, please step forward. Great! Now we just move the largest number to the beginning.
10 minus 6 equals 4, and 10 minus 4 equals 6. Next group, please! Would 3, 8, and 11 take the stage? With the largest number, please step forward. Great!
Okay, biggest number, please move to the beginning.
11 minus 8 equals 3, and 11 minus 3 equals 8. Now you try a few:
8 plus 4 equals 12, so 12 minus 8 equals 4. Right, 4 and 12 minus 4 equals 8. That’s right, 8!
Let’s try another.
1 plus 9 equals 10, so 10 minus 9 equals 1. Right, and 10 minus 1 equals 9.
Right, 12 minus 5 equals 7, 9 minus 1 equals 8, 11 minus 10 equals 1, 9 minus 7 equals 2, 10 minus 3 equals 7, and 11 minus 7 equals 4.
