- Don't use plastic water bottles, or buy cases of bottled water. Use a stainless steel or glass bottle, and a water filter.
- Turn off some classroom lights on sunny days.
- Skip Dixie cups, etc. and ask friends/families to donate old coffee cups, mismatched metal utensils for classroom parties and celebrations.
- Save memos, start-of-school paperwork, etc and use as scrap paper throughout the year, instead of Post-It notes.
- Turn off your computers before you go home.
