Interactive Sprites, Sound, and Debugging

This unit guides learners through building richer interactive projects by adding and controlling sprites, costumes, text-to-speech, and instrument sounds while introducing cloning, string operations, and simple parallel processing. Students will practice systematic debugging, saving/testing workflows, transfer programs to a micro:bit, and prepare projects for sharing, building on foundational coding concepts and preparing for more advanced program design in the next unit.

Learning Objectives

• Apply block-based programming constructs to create and modify sprites and costumes, add text-to-speech and instrument sounds, and assemble a multi-sprite interactive program
• Demonstrate systematic debugging and testing workflows — including commenting out code, iterative testing, and use of save/revert strategies — to identify and fix functional and timing errors
• Analyze and implement cloning, parallel processing, and string manipulation techniques to coordinate simultaneous sprite behaviors and generate dynamic emoji-based outputs
• Evaluate program portability and community sharing by transferring projects to a micro:bit, documenting design decisions, and preparing work for publication and peer review
