Thanks for asking! Different size and color Post-its are a mainstay for me. Colored markers or pens around. Depending on what you are teaching, it's nice to have a large table in the center of the room for discussion, then tables around the walls with computers on them so the cables don't get out of control. Make sure the sound system is good for the music and if possible, have it come from the back of the room (auditory people who might be bothered by the music tend to sit in the front). I pass out pipe cleaners occasionally for difficults topics so learners can fidgit, or little cans of playdough. Where are your schools? I'd love to visit one! I'm also a big supporter of flipcharts or enough white boards so student work is up on the walls a lot. When I was at AT&T 25 years ago, our state-of-the-art classrooms were painted slightly darker about two feet from the floor and ceiling, so the eye was drawn to the center of the room (the instructor). There were also no corners in the room - they were all rounded off. There was some research at that time that sitting near a corner isolated people. Lou Russell
