Have you ever wondered how computers can do so many things so quickly? It’s all thanks to something called programming! When you teach a computer to do a task, you can save that task as a “function” and use it whenever you need. It’s like giving the computer a new word in its language!
Imagine you want to draw a square. You would need to move forward and turn four times. Instead of doing this every time, you can create a function called “draw a square.” This way, whenever you want to draw a square, you just use your “draw a square” function, and the computer does all the steps for you. It’s like having a magic button that does the work!
In our coding puzzle, we’ve already made a “draw a square” function for you. You’ll see it as a green block in your toolbox. Your job is to write the code that draws a square and put it inside this function. Here’s how you do it:
Now, you can use the “draw a square” function block just like any other block to solve the puzzle. It’s a fun and easy way to make your code more powerful!
Functions make coding easier and faster. Once you’ve created a function, you can use it over and over without having to write the same code again. This helps you solve problems more efficiently and makes your programs easier to understand.
So, next time you’re coding, think about what tasks you can turn into functions. You’ll be amazed at how much you can do with just a few simple steps!
Imagine a shape you’d like to draw, like a triangle or a star. Write down the steps needed to draw it. Then, create a function for your shape using the steps provided in the article. Share your function with a classmate and see if they can use it to draw the shape!
Work in teams to create a series of functions that, when combined, draw a picture. Each team member creates one function, and then you all put them together to see the final result. The first team to complete their picture wins!
Write a short story where each action is a function. For example, “walk to the park” could be a function that includes steps like “put on shoes” and “open the door.” Share your story with the class and discuss how functions help organize your actions.
Swap functions with a partner and try to find any mistakes or improvements in their code. Discuss what you found and how you can make each function better. This will help you understand how to write clear and efficient code.
Create a piece of digital art using functions to draw different shapes and patterns. Display your artwork in a virtual gallery and explain how you used functions to create it. This will show how coding can be both logical and creative!

One of the great aspects of computer programming is that once you’ve taught a computer how to perform an action, you can call that function again. You give it a name, and then you can invoke it whenever needed. This is similar to extending the language.
In the program we built, we learned how to draw a square by moving and turning four times. We can take that function and name it “draw a square,” so that whenever we want to perform that action, we simply say “draw a square,” and it will execute that function for us. We’ve incorporated this concept into our programming language.
In this puzzle, we have already created a “draw a square” function for you. You’ll find it in the toolbox as a green block. What you need to do is write the same code you used before to draw a square and place it in this function. To do this, click on the edit option in the green “draw a square” block. This will open the function editor.
The function editor has three parts: a place to name your function (which will appear on the green block), a short description of what your function is supposed to do (in this case, it’s supposed to draw a square), and a workspace below where you can drag and drop blocks from the toolbox.
Remember to place the blocks that create a square inside the green wrapping block for the function. Once you’re finished, click on save and exit. This will take you back to the main puzzle workspace. Now you can use the “draw a square” function block just like any other block to solve the puzzle.

Coding – The process of writing instructions for a computer to follow. – Example sentence: In our computer class, we learned that coding can help us create fun games and apps.
Function – A set of instructions grouped together to perform a specific task in a program. – Example sentence: We used a function to make the character jump every time we pressed the space bar.
Square – A shape with four equal sides, often used in coding to create graphics or designs. – Example sentence: In our coding project, we drew a square on the screen using simple commands.
Computer – An electronic device that processes data and performs tasks according to a set of instructions. – Example sentence: We used the computer to write and test our coding projects in class.
Programming – The act of creating a set of instructions for a computer to perform specific tasks. – Example sentence: Programming allows us to build websites, games, and even robots.
Toolbox – A collection of tools or commands available in a coding environment to help create programs. – Example sentence: The toolbox in our coding software had all the blocks we needed to build our game.
Blocks – Visual pieces used in some coding languages to represent commands or actions. – Example sentence: We connected different blocks to make the character move across the screen.
Workspace – The area in a coding environment where you can arrange and connect blocks or write code. – Example sentence: My workspace was filled with colorful blocks that made my robot dance.
Tasks – Specific actions or jobs that a program is designed to perform. – Example sentence: Our coding challenge was to complete all the tasks to make the robot reach the finish line.
Code – The language or instructions written to create a program or software. – Example sentence: We wrote code to make the computer display a message when we clicked the button.
