How To Comment On Scratch (The Easiest Way)

In the vibrant world of coding, Scratch stands out as a user-friendly platform designed to introduce kids to the fascinating realm of programming. As part of this interactive environment, commenting on Scratch projects plays a crucial role in fostering learning, collaboration, and creativity. This article serves as a comprehensive guide on how to comment on Scratch, specifically tailored for young learners.

Scratch Coding For Kids

Before delving into the intricacies of commenting, let’s highlight why Scratch is a preferred choice for coding education, especially for kids.

Developed by the MIT Media Lab, Scratch employs a visual programming language that utilizes colorful blocks, making coding accessible and enjoyable for young minds.  

In essence, Scratch provides an ideal environment for kids to explore and express their creativity through coding. The platform’s combination of visual programming, engaging projects, and a supportive community creates a dynamic and child-friendly space where young learners can develop not only coding skills but also critical thinking, problem-solving, and teamwork.

As we understand how to comment on Scratch, it is important to recognize that the platform’s unique features are intentionally crafted to make coding an accessible and enjoyable experience for kids. Scratch is not just a coding tool; it is a colorful canvas where young imaginations can flourish, and the adventure of coding begins with a palette of vibrant blocks and boundless creativity.

What Are Comments In Scratch?

Imagine coding as an adventure, and your code is like a treasure map with lots of twists and turns. Now, comments in Scratch are like little signs or notes you leave along the way to help you and others understand the map better.

Comments serve as valuable annotations within the code that provide additional information, explanations, or context. In Scratch, comments are text-based notes added to specific parts of a project to describe the purpose of blocks or provide guidance to other users. 

In Scratch, instead of writing more code, you can add these notes (comments) to explain what different parts of your project do. It is like telling a story about why you put specific blocks together. These comments are there to guide anyone who looks at your project, making it easier for them to figure out what you did.

Think of comments as friendly tips or messages you share with your coding friends. When you and others work on projects, these comments become a way to talk to each other about the code. They’re like sticky notes that say, “Hey, this block does this, and here’s why!”

So, in simpler terms, comments in Scratch are like helpful notes that make coding less confusing, and more fun, and let everyone in the Scratch community understand and enjoy your creations!

Understanding how to use comments effectively is a skill that not only enhances coding comprehension but also encourages collaboration.

How To Comment on Scratch [Step-by-Step Guide]

Comments act as navigational aids, providing a roadmap for coders to traverse the intricate landscape of their creations. By strategically placing comments, users can mark milestones, highlight key functionalities, and demystify complex sections, making it easier for themselves and others to understand the logic behind the code.

Let’s take a closer look at the simple and user-friendly steps involved in adding comments to your Scratch project. By breaking down the process into easy-to-follow steps, you’ll find that commenting in Scratch is a breeze.

Step 1: Access the Scratch Project

Start by opening the Scratch project where you want to add comments. This could be a project you’re currently working on or one that caught your eye from another user. The key is to be in the project where you want to share your thoughts or explanations.

Step 2: Locate the Block to Comment

Once you have opened the project, identify the specific code block or section where you want to add a comment. Comments are like little notes you attach to specific parts of your code, so think about where it would be most helpful to provide extra information. This is often done to explain tricky code or describe what a particular block does.

Step 3: Right-click on the Block


To add a comment, right-click on the block you’ve chosen. This action opens up a drop-down menu – a small box of options that appears when you right-click. It is like a toolbox that holds everything you need to work on that block.

Step 4: Select “Add Comment”

Within the context menu, you’ll see various options. Look for and choose the “Add Comment” option. Think of this as opening a space to jot down your thoughts or explanations about the block you selected. It is like saying, “I want to share something about this part of the code.”

Step 5: Type Your Comment

After selecting “Add Comment,” a text box as shown below will pop up. This is where the magic happens! Type in your comment – it could be an explanation, a reminder, or any information that helps others (or yourself) understand the purpose of the block. This is your chance to add your voice to the code.


Step 6: Save Your Comment

Once you’ve typed in your comment, it’s time to save it. This ensures that your comment sticks around and is visible whenever someone hovers over or clicks on the associated code block. Saving your comment is like pressing the “OK” button – it tells Scratch, “Yes, I want this note to be part of my project.”

By following these straightforward steps, you’re not just adding comments; you’re enhancing your project with valuable insights and creating a more collaborative and understandable coding experience for yourself and others.

Types of Comments in Scratch

Understanding the various types of comments in Scratch is essential for effective communication and collaboration. Scratch supports two main types of comments:

Full Comment

A full or multi-line comment in Scratch is like a detailed note or a mini story attached to a specific block of code. It allows you to provide comprehensive explanations, instructions, or context about the purpose and functionality of a particular code segment.

Full comments are Ideal for complex code sections, detailed algorithms, or when you want to share the reasoning behind your coding choices. Full comments are valuable when you need to guide others (or yourself) through intricate parts of your project.

Mini Comment

A mini or Single-Line comment, on the other hand, is a concise and brief note attached to a code block. It is designed to provide quick, to-the-point information about the purpose or functionality of a specific block.

They are ideal for simple code blocks, straightforward functionalities, or when you want to add a quick note without overwhelming the code with too much detail. Mini comments are like handy post-it notes for your code.

Uses of Comments in Scratch

Comments in Scratch serve a multitude of purposes, contributing to a richer coding experience. Let’s look at a few uses of comments on Scratch:

Explanation of Code Logic

Comments help explain the logic behind specific code blocks, making it easier for others (or yourself) to understand the purpose of each element.

Collaboration and Sharing

When users share their projects, comments enhance collaboration by providing insights into the thought process behind the code. This collaborative aspect is central to the Scratch community.

Teaching and Learning

For educators and learners alike, comments become invaluable teaching tools. They guide learners through projects, offering explanations and facilitating the learning process.

Debugging Assistance

When troubleshooting or debugging code, well-placed comments can provide clues and insights into potential issues.
