**Additional Notes:**

* Ensure to regularly engage with students via Zoom, encouraging questions and discussions.
* Monitor Miro/Mural Kanban boards to track student progress and intervene when necessary.
* Use the breakout room feature effectively for peer learning and to address specific queries.
* Follow up with a summary email including key points and resources from the lesson.
