Sprites, Variables, and micro:bit

This unit guides students through building interactive block-based projects that combine sprite design, cloning, variables, radio communication, and physical deployment to the micro:bit. Students will plan with flowcharts and brainstorming, implement game logic and gadget behavior, then test, debug, enhance, and share their programs.

Learning Objectives

• Construct interactive sprite-based programs using costumes, clones, and event blocks to implement hide-and-seek style game mechanics
• Apply variables and on-radio/on-shake event blocks to generate, send, and receive randomized values and identify winners, then deploy the program to a micro:bit
• Demonstrate systematic testing and debugging practices by saving, iteratively testing both in the simulator and on-device, identifying and fixing at least two defects, and sharing the working program
• Analyze and plan program structure using brainstorming and flowcharts, then evaluate and implement at least two scene or gadget enhancements to improve usability or appearance
