Hello friends! Today, we’re going to learn about something super cool in math called powers. Powers are a fun way to show multiplication using the same number over and over. Let’s dive in and see how easy it is!
A power is a special way to write a multiplication problem where you multiply the same number several times. When we write a power, it looks like this: a big number with a little number up top. The big number is called the base, and the little number is called the exponent.
Reading powers is simple! You say the base first, then “raised to the power of,” and finally the exponent. For example, if you see 54, you say “five raised to the power of four.” Let’s try a few more:
Now, let’s learn how to calculate powers. The exponent tells us how many times to multiply the base by itself. For example, in 23, the base is 2, and the exponent is 3. So, we multiply 2 by itself three times: 2 x 2 x 2 = 8. So, 23 equals 8.
Let’s try another one: 34. We multiply 3 by itself four times: 3 x 3 x 3 x 3. First, 3 x 3 = 9, then 9 x 3 = 27, and finally, 27 x 3 = 81. So, 34 equals 81.
Try calculating this power: 43. Ready? Let’s go! Multiply 4 by itself three times: 4 x 4 = 16, and 16 x 4 = 64. So, 43 equals 64. Great job!
Here’s a fun fact: when a number is raised to the power of 2, we can say it’s “squared.” For example, 42 is “4 squared.” When a number is raised to the power of 3, we say it’s “cubed.” So, 53 is “5 cubed.” These terms are used a lot, so remember them!
That’s it for today! We’ve learned a lot about powers. Keep practicing, and you’ll become a power expert in no time. See you next time for more fun math adventures!
Power Hunt: Go on a “power hunt” around your home or classroom. Look for objects that come in groups or sets. For example, a pack of crayons, a set of chairs, or a stack of books. Try to express the total number of items using powers. For instance, if you find a set of 4 chairs in 3 rows, you can say it’s 43. Share your findings with your friends or family!
Power Art: Create a piece of art using the concept of powers. Draw or use craft materials to make a picture that represents a power. For example, draw a tree with branches that double at each level to show 23. Explain your artwork to someone and describe how it represents a power.
Power Story: Write a short story or comic strip about a superhero whose powers increase exponentially. Describe how their strength or abilities grow using powers. For example, “Super Sam’s strength was 22 on Monday, but by Friday, it was 25!” Share your story with the class and discuss how powers can be used to describe growth or change.
Sure! Here’s a sanitized version of the transcript:

Hello friends! I just made a video for my math channel, and it turned out great! It’s about calculating powers. Do you know how to calculate them? Don’t worry, just click play, and you’ll see how easy it is!
Hello again, math friends! Today we’re going to explain powers. A power is a short way to represent a multiplication operation made up of several identical numbers.
Look, this is how we write powers. I hope you’ve seen something like this before. A power is made up of two numbers: this big one here and this little one here. So how do we read powers? It’s very easy! We read them like this: five raised to the power of four.
First, we read the bigger number, then we say “raised to the power of” and read the smaller number up here. Easy, right?
How would you read this power: six raised to the power of three? Well done! And this one: eight raised to the power of six? Awesome! How about this one: ten raised to the power of eight? You got this!
The bigger number is called the base. Repeat after me: base. Great! The smaller number is called the exponent. Repeat after me: exponent. Way to go!
Now let’s see how we calculate powers. The exponent tells us the number of times we should multiply the base by itself. Let’s look at the example we have on the screen: 2 to the power of 3. As we said before, the base of this power is 2, and the exponent is 3, which is the number of times we should multiply the base.
So, 2 to the power of 3 is 2 times 2 times 2, which equals 8. This means that 2 to the power of 3 is 8. The result of this multiplication is called power. Easy, right?
Let’s look at another example. This one is easy: 3 to the power of 4. What do we need to do? We need to multiply the base by itself the number of times indicated by the exponent. This means that we should multiply three by itself four times.
Let’s look at the result: three times three times three times three equals… Hmm, maybe it’s better to multiply separately. Three times three is nine, nine times three is twenty-seven, and twenty-seven times three is eighty-one. Awesome! Three to the power of four is eighty-one.
Would you like to try doing one yourself? Calculate this power: four to the power of three.

Time’s up! Do you have the answer? Let’s see. To calculate 4 to the power of 3, we should multiply 4 by itself 3 times. Four times four is sixteen, and sixteen times four is sixty-four. So, four to the power of three is sixty-four. Well done, everyone!
Here’s a little secret: did you know that when a number is raised to the power of two or three, it can be read differently?
[Music]
When a number is raised to the power of two, we can also say “squared.” For example, 4 raised to the power of 2 or 4 squared. Remember this expression; it is used very often. Also, when a number is raised to the power of 3, we can say “cubed.” So this would be 5 raised to the power of 3 or 5 cubed.

We use this expression a lot as well, so don’t forget it! My video looks great! I’m going to upload it to my channel so that children from all over the world can learn about powers. See you soon!
