List thing that a healthy living teacher can do to improve a class or learning environment

1- Set clear behavior expectations from the first day of school and stick to them throughout the year.
2-Have a no-bullying tolerance policy with clear consequences.
3-Spend time building the classroom community and discussing how students are more alike than different.
4-Adopt “bucket filler” thinking and encourage students to point out the positive. Hang up motivational posters to keep kids in the right mindset.
5-Model being the positive person you want your students to be from the moment they enter the classroom.
6-Create a class “Get Fit” routine and take daily fitness breaks even if it is just for five minutes.
