Hello, friends! Welcome to our exciting adventure with function machines. Today, we’re going to have loads of fun figuring out some cool math rules. Are you ready? Let’s get started!
Imagine a magical box that changes numbers. You put a number in, and it gives you a different number out. Our job is to find out what magic rule the box is using!
Let’s start with the green box. We put in the number 4, and out comes 8. Hmm, what could the rule be? Let’s try adding 4. If we add 4 to 4, we get 8. Yay, that’s right!
Now, let’s try with 9. If we add 4 to 9, we get 13. Let’s count: 9, 10, 11, 12, 13. Perfect!
Next, we have 3. Adding 4 gives us 7. Let’s count: 3, 4, 5, 6, 7. Awesome!
Now, let’s look at the purple box. We start with 8 and get 6. This time, we need to subtract. Let’s try taking away 2. 8 minus 2 is 6. Correct!
Let’s check with 11. If we subtract 2, we get 9. Great!
Next, we have 16. Subtracting 2 gives us 14. Perfect again!
Time for the orange box! We start with 10 and need to get to 3. Let’s subtract 7. 10 minus 7 is 3. Yay!
Now, let’s try 14. Subtracting 7 gives us 7. Correct!
Next, we have 18. Subtracting 7 gives us 11. Awesome!
Let’s move on. We start with 3 and want to get to 8. Let’s add 5. 3 plus 5 is 8. Yay!
Now, let’s check with 10. Adding 5 gives us 15. Perfect!
Next, we have 12. Adding 5 gives us 17. Great job!
Now, let’s look at the blue box. We start with 2 and want to get to 13. Let’s add 11. 2 plus 11 is 13. Correct!
Let’s check with 5. Adding 11 gives us 16. Awesome!
Finally, we have one more box. We start with 9 and want to get to 0. Let’s subtract 9. 9 minus 9 is 0. Yay!
Now, let’s check with 16. Subtracting 9 gives us 7. Perfect!
Lastly, we have 18. Subtracting 9 gives us 9. Great job!
Wow, you did an amazing job figuring out all the rules for the function machines! Thanks for joining me on this fun math adventure. See you next time for more exciting learning. Bye!
Create Your Own Function Machine: Use a small box or a shoebox to create your own function machine. Decorate it with colorful paper and stickers. Then, choose a simple rule like adding 2 or subtracting 1. Write down a few numbers on small pieces of paper, put them into the box, and let your family or friends guess the rule by seeing the numbers that come out. This will help you understand how function machines work and practice your math skills!
Function Machine Walk: Go on a walk around your neighborhood or school and look for numbers on signs, houses, or cars. Choose a simple rule, like adding 3 or subtracting 2, and apply it to the numbers you see. For example, if you see the number 5 on a sign and your rule is to add 3, then the new number is 8. Share your findings with a friend or family member and see if they can guess your rule!
Function Machine Story Time: Write a short story about a magical function machine that helps a character solve a problem. Think about what rule the machine uses and how it helps the character. Draw pictures to go along with your story. Share your story with your class or family and explain how the function machine works in your story. This will help you think creatively about how function machines can be used in different situations.
Sure! Here’s a sanitized version of the YouTube transcript:

Welcome to Kids Academy! Hello everyone! Let’s open the worksheet. Don’t forget to like this video and subscribe to our channel. You can find the link to this app in the comments below.
Today, we have a new worksheet that is lots of fun! The name of our worksheet is “Find the Rule.” The directions say to check the correct rule for each function machine. Each of these colored boxes represents our function machines, and we need to find the rule that makes sense for each one.
Let’s start with the first one, the green function machine. It says “input” and “output” on either side. Input is what we start with in our machine. Let’s start with the first number, which is 4, and our output is 8. So, I will turn this into an equation: 4 at the beginning and 8 at the end. Now, we need to figure out the rule that makes sense.
What do we need for 4 to become 8? We have a few options: plus 3, plus 4, or plus 5. Let’s go through and see what makes sense.
First, let’s try 4 plus 3. That equals 7, which is not correct. So, let’s try the next one: 4 plus 4. That equals 8, which is correct!
Now, let’s check the next input, which is 9. If we use plus 4, we have 9 plus 4 equals 13. Let’s count up from 9: 10, 11, 12, 13. That works!
Next, we have 3 plus 4 equals 7. Let’s count up from 3: 4, 5, 6, 7. That’s correct!
Now, let’s move on to the purple function machine. We start with 8, and we need to get to 6. Since we are going from a larger number to a smaller number, we will subtract.
Let’s try 8 minus 2. That equals 6, which is correct! Now, let’s check 11 minus 2. That equals 9, which is also correct.
Next, we have 16. If we take away 2, we should get 14. That works too! So, our answer is minus 2.
Now, let’s go to the orange function machine. We start with 10 and need to get to 3. We will subtract.
Let’s try 10 minus 7. That equals 3, which is correct! Now, let’s check 14 minus 7. That equals 7, which is also correct.
Next, we have 18 minus 7. That should equal 11. Let’s count: 18, subtract 7, and we get 11. That’s correct!
Now, let’s move on to the next function machine. We start with 3 and need to get to 8. We will add.
Let’s try 3 plus 4. That equals 7, which is not correct. So, let’s try 3 plus 5. That equals 8, which is correct!
Now, let’s check 10 plus 5. That equals 15, which is correct.
Next, we have 12 plus 5. That equals 17, which is also correct! So, our answer here is plus 5.
Now, let’s go to the blue function machine. We start with 2 and need to get to 13. We will add.
Let’s try adding 11. So, 2 plus 11 equals 13. That’s correct!
Now, let’s check 5 plus 11. That equals 16, which is also correct!
Finally, we have one more function machine. We start with 9 and need to get to 0. To get to zero, we will subtract 9.
So, 9 minus 9 equals 0, which is correct!
Now, let’s check 16 minus 9. That should equal 7. If we count, we get 7, so that’s correct!
Lastly, we have 18 minus 9. That equals 9, which is also correct!
Great job today! Thank you for working through this with me and finding the rules for the function machines. I’ll see you again next time! Bye!
