We keep six classroom commitments in our classroom. We call them commitments instead of rules. This ideology is based from Conscious Discipline (https://consciousdiscipline.com/). I teach a preschool classroom of 3-4's and they do great with these. We go over them daily before we start our day.
Polka dots display for classroom rules included:
I will listen to my teacher
I will be nice to others
I will keep my classroom clean
I will keep my body calm
I will play safely
I will use gentle touches
Posters measures around 7.5 inches by 9.75 inches. Poster orientation is in landscape.
If there is a rule you need that is not available, contact me and I can provide more. Rules be in the I will format
