One classroom. The full context.
A lesson tree keeps activities, visibility and student work together. Inspect a lesson or activity without changing its state.

A lesson is one gate. An activity is another.
Opening a lesson does not release all its activities. Locking the lesson locks its activities too; releasing an individual activity opens its lesson.
Finished does not mean gone.
Completed lessons remain inspectable in the classroom tree. The instructor can return to their materials and student work.
