Facilitator's Guide and Materials: Lesson 3 Radio and If Statements

Run the lesson here; the student item below remains the independent and absence route.

Daily Learning Contract

Topic: Radio communication and conditional response

Objective: Students will explain how a shared radio channel and conditional rule control a micro:bit's response, then apply both concepts in a two-device message system.

Demonstration of learning: Completed Lesson 3 worksheet, working sender and receiver programs, and checkpoint evidence explaining the message condition and resulting response.

Before class

Time: One class period
Student route: Learn: Lesson 3 Radio and If Statements
Use what already exists: Keep existing guide, presentation, worksheet, printable checkpoint, and RISE route.

Lesson flow

1. Launch: Launch with a concrete question or failure that makes wireless messages and conditionals matter.
2. Model: Model one current example or tool move before students begin.
3. Do: Guide the first decision together, then release students to the existing Canvas task.
4. Check + support: Check for the named evidence, not completion alone; keep a visual sequence, sentence stems, and purposeful partner roles available.
5. Close + handoff: Collect or verify the evidence and name the next lesson's connection.

Check before students leave

Ask students to point to the specific evidence above and explain one choice, test, or revision. Completion alone is not evidence of understanding.

Support + troubleshooting

Scaffold: Keep the visual task sequence visible, assign purposeful partner roles, and use the sentence stems on the student page before simplifying the task.

When students get stuck: Ask for the exact step where the tool, code, or task stopped. Check setup, inputs, and saved work before replacing the task or lowering the thinking.
