10 Fun Activities to Get K-12 Students Excited About Computer Science
Computer science can sound intimidating to students at first, especially if they picture it as just lines of code on a black screen. But in reality, it’s a creative, interactive, and problem-solving playground that can be fun at any age. At Rex K-12, we believe that the best way to get students engaged in computer science is to show them just how exciting and accessible it can be.
Whether you’re a teacher looking for fresh ideas or a parent wanting to introduce your child to tech skills, here are 10 fun activities that can spark excitement and build confidence in computer science for students from kindergarten through 12th grade.
1. Build a Game with Scratch
Scratch is a visual programming language that lets kids drag and drop blocks to create animations, stories, and games. It’s perfect for younger learners and provides instant feedback, which keeps students engaged.
2. Code a Personal Website
Middle and high school students love the idea of creating something of their own. A simple HTML/CSS project where they build a personal blog or portfolio helps them connect computer science to real-world skills.
3. Create a Virtual Pet or Avatar
Have students design a digital pet or avatar that they can interact with using code. Platforms like Scratch allow them to animate responses based on user inputs, teaching logic and sequences in a playful way.
4. Unplugged Coding Challenges
Coding doesn’t have to happen on a screen. Use index cards, board games, or printable mazes to help students learn algorithms, loops, and debugging offline. It’s especially effective in early grades or when screen time needs to be limited.
5. Participate in an Hour of Code
The Hour of Code initiative offers hundreds of free, fun, and beginner-friendly coding activities for every age group. It’s a great way to introduce coding during a class session, after school, or even at home.
6. Try a Cybersecurity Escape Room
Create a classroom (or virtual) escape room using cybersecurity challenges like decoding messages, spotting phishing scams, or building strong passwords. It turns learning about digital safety into a thrilling experience.
7. Animate a Story with Code
For students who love storytelling, challenge them to write and animate their own stories using block-based coding platforms. They’ll learn sequencing, conditionals, and character design—all while bringing their ideas to life.
8. Use AI Tools to Explore Machine Learning
Older students can experiment with beginner-friendly AI platforms to see how machines learn. Tools like Teachable Machine from Google allow them to train their own models using images, sound, or poses.
9. Create a Music or Art Generator
Combine creativity with coding by having students use platforms that let them compose music or create digital art through code. It’s a great way to show that computer science isn’t just technical—it’s also artistic.
10. Join a Rex K-12 Summer Camp or After-School Program
Our programs are designed to turn curiosity into confidence. Whether your student wants to try game development, web design, or cybersecurity, Rex K-12 offers flexible, fun, and project-based learning that builds real-world skills.
Final Thought: Make It Meaningful and Fun
The goal isn’t to turn every student into a software engineer—it’s to help them realize that computer science is accessible, creative, and full of opportunities. By introducing coding and technology through fun, age-appropriate activities, we’re not just teaching skills—we’re opening doors.
