    Results

Checkpoint: ready to move on?

Every learner has a marked Task C grid, with feedback and a reassessment date where needed.

Extension for fast finishers

Log conditions and vent events to Serial with RTC timestamps.

Catch-up path

Learners marked NYC prepare the missed criteria for S49.

Homework and practice

Choose the extension topics that support the final project.

Facilitator notes

  • Task C demonstrations take longer than Tasks A and B. If needed, finish the last few at the start of S47.
