Master Scratch: Advanced Coding for Kids
Ready to think like a real programmer? This advanced Scratch course takes young coders to the next level with custom blocks, algorithms, data structures, and powerful extensions like video sensing, music, and pen drawing.
You'll explore recursion, optimization, and real-world simulations, building everything from fractal art to ecosystem models, then wrap it all up with a capstone project where you design and pitch your very own original game or app.
Best for kids who have completed beginner and intermediate Scratch and are ready for their biggest challenge yet.
