ClassX Video Lessons Youtube Channel Smile and Learn English Multiply by 10, 100 and 1000 ???? MENTAL MATH TRICKS for Kids ???? Episode 1
Hello, my friends! Are you ready to learn some cool tricks to multiply numbers super fast? Today, we’re going to become Mental Math Stars by learning how to quickly multiply by 10, 100, and 1,000. Let’s get started!
Let’s begin with multiplying by 10. Imagine there are three space stations, and each one has 10 astronauts. How many astronauts are there in total? Instead of multiplying the traditional way, we can use a trick. We take the number 3 and add a zero because 10 has one zero. So, 3 times 10 equals 30. That means there are 30 astronauts in total!
Now, let’s see how many stars are in three constellations if each one has 100 stars. We can use our trick again! We write the number 3 and add two zeros from the number 100. So, 3 times 100 equals 300. There are 300 stars in total!
Next, let’s find out how many aliens live on five planets if each planet has 1,000 aliens. To multiply by 1,000 quickly, we write the number 5 and add three zeros from the number 1,000. So, 5 times 1,000 equals 5,000. There are 5,000 aliens in total!
Who wants to try it? Let’s practice:
Awesome! Now you know how to multiply by 10, 100, and 1,000 quickly and easily. Use these tricks whenever you need to calculate something fast. Keep practicing, and you’ll become even better!
We’ve learned so much today! There are many more fun videos to explore. Imagine all the things you can learn! Keep watching and have fun learning!
Zero Hunt: Go on a “Zero Hunt” around your home or classroom. Look for items that come in groups of 10, 100, or 1,000. For example, you might find a box of 10 crayons, a pack of 100 sheets of paper, or a jar with 1,000 beads. Count them together and practice writing the numbers with the correct number of zeros. Discuss why adding zeros makes the number bigger.
Number Building Blocks: Use building blocks or LEGO pieces to represent numbers. Assign each block a value of 10, 100, or 1,000. Build structures using these blocks and calculate the total value by adding zeros. For example, if you have 4 blocks of 10, stack them and say, “4 times 10 equals 40!” Encourage creativity by building different structures and calculating their values.
Everyday Multiplication: Ask your child to observe and find examples of multiplication by 10, 100, or 1,000 in everyday life. For instance, if you see a pack of 10 juice boxes, ask, “How many juice boxes would there be if we had 3 packs?” Encourage them to use the mental math trick to find the answer. Discuss how this trick can help in real-life situations.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello, my friends! I’m back to show you some amazing tricks that will help you multiply numbers really fast. Ready to become Mental Math Stars? Today, we’ll learn how to quickly multiply by 10, 100, and 1,000 with a few little tricks. Here we go!
Let’s start by learning the trick to multiply any number by 10. For example, how many astronauts are there on three space stations if 10 astronauts live in each? We can multiply three times 10 to find out how many astronauts there are in total. Instead of traditional multiplication, we can use our trick: we start with the number three and then add a zero since 10 has only one zero. That means if we have three space stations with 10 astronauts in each, there are 30 astronauts in total.
Now, how many stars are there in three constellations if each one has 100 stars? To find out, we can multiply the traditional way, but we want to do it faster. We write the number three and then simply add two zeros from the number 100. So, there are 300 stars in total.
Next, how many aliens live on these five planets if each planet has 1,000 aliens? To quickly multiply by 1,000, we write the number five first and then add the three zeros from the number 1,000. So, if we have five planets and 1,000 aliens live on each, there are 5,000 aliens in total.
Now, who wants to try it? Let’s practice together! What is 9 times 10? Great, it’s 90! First, we put the nine and add one zero because we are multiplying by 10. What is 8 times 100? Very good, it’s 800! First, we put the eight and add two zeros because we’re multiplying by 100. What is 2 times 1,000? Exactly, it’s 2,000! We put the two first and add three zeros because we’re multiplying by 1,000.
Great! Now you know how to multiply by 10, 100, and 1,000 quickly and effortlessly. Use these tricks whenever you need to calculate something fast. See you next time, little math stars!
