I have used these 4 simple classroom rules for Pre-K for over 10 years. They have worked well because they cover everything, and are simple enough for young children to remember. I always tell my students the most important rule is “Be nice to others” and I always put that poster first.
I have made these printable rules posters for use in your classroom. These can be posted on the wall, and I also recommend making a book with them to place in the reading center.
I have three different versions below, so you can choose the colors you like best.
If you like these, you might also be interested in these sets on Teachers Pay Teachers that compliment the posters:
