Grouping: Pairs or individual
Take-home: Small working circuit; reusable breadboard stays at school
Key ideas: Breadboard layout, closed circuits, polarity, series/parallel possibilities, troubleshooting.
Start with: Build a tiny LED circuit live without soldering.
Success check: Student creates at least one functioning circuit and can explain the current path.
Try changing: Number/color of LEDs; switch placement; resistor value if appropriate.
Preparation: Pre-test breadboards; create three challenge cards from easy to open-ended.
Lesson flow: Day 1: Breadboard orientation demo → complete one starter circuit → guided choice challenge → share/troubleshoot
Safety and cleanup: Low-voltage only; teacher checks battery connections; LEDs/resistors are small parts.
