We are using a new program at our school this year called RULER. Instead of rules, we came up with a Classroom Charter. It was labor intensive and really challenged the kids to think, but I love how it came out.
"A Mind Jar is a meditation tool to use whenever a child feels stressed, overwhelmed or upset. Imagine the glitter as your thoughts. When you shake the jar, imagine your head full of whirling thoughts, then watch them slowly settle while you calm down".
