I learned a long time ago that students cannot sit for long periods of time. This notion applies to people who are 5 and 50! Adults can sit longer than kindergarteners (sometimes) but still need choice and movement.
I learned from Dr. Jean to have students cross the midline of their body to reenergize. For my adult meetings I learned to incorporate brain drainers.
Students need to be engaged. Sometimes this looks like brain work and sometimes it is movement.
I always like for students to make judgements and place themselves physically in different part of the room to “show” their answers.
