Learning to code has become an essential skill for students in today’s digital age. Scratch programming provides an excellent platform for school students to start their coding journey. With its intuitive visual interface and block-based coding system, Scratch makes coding enjoyable for students of all ages.
Program and Programming Language
A computer follows stepwise instructions to complete any task, which is known as program. Also known as software, a program tells the computer what to do.

Everything that a computer does, from starting up to shutting down is done by a program. Any game that you play on your phone or computer is nothing but a program. Even the viruses written for the computer are programs.
The language used to write programs is called a programming language and the person who writes these programs is known as a programmer.
What is Scratch?
Scratch is a beginner-friendly programming language (developed by the Lifelong Kindergarten Group at the MIT Media Lab) that allows students to create interactive stories, animations, and games.
Instead of typing lines of code, you need to drag and snap colorful code blocks together, which makes it easy to understand and experiment with coding concepts.
Learning Scratch programming promotes computational thinking, problem-solving, and logical reasoning. It enhances creativity by allowing students to express their ideas through animations, stories, and games.
Scratch also introduces students to foundational programming concepts, laying a solid groundwork for learning other programming languages in the future.
Main Features in Scratch
To begin coding with Scratch, one can access the Scratch website (scratch.mit.edu) or download the offline version called Scratch Desktop. The platform provides an extensive library of sprites (characters) and sounds that students can use in their projects. They can also create their own sprites or import images and sounds.
Blocks and Scripts
In Scratch, coding is done by stacking blocks together to create scripts. Blocks come in different categories such as motion, looks, sound, and control. Students can drag blocks from these categories and snap them together to form instructions for their sprites. For example, combining a “move 10 steps” block with a “turn 90 degrees” block can make a sprite move in a square pattern.
Events and Control
Scratch allows students to control the behavior of their projects using event blocks. They can trigger actions when certain events occur, such as when a sprite is clicked, a key is pressed, or a timer reaches a specific value. These event blocks provide a dynamic and interactive experience.
Variables and Loops
Students can use variables in Scratch to store and manipulate data. They can create variables to keep track of scores, levels, or any other values relevant to their project. Loops, such as the “repeat” block, allow students to repeat a set of actions multiple times, making it useful for creating patterns or iterating through lists.
Closing Thoughts
Scratch programming provides an engaging way for school students to learn coding. Its visual interface, block-based coding system, and vibrant online community make it an ideal platform for beginners. By exploring Scratch, students can improve their creativity, develop logical thinking, and acquire valuable coding skills that will benefit them later in life. The key to mastering Scratch programming lies in practice and experimentation. You must encourage the student to explore different projects, share their creations, and collaborate with their peers.
