One of my favorite things to do each week with my class is Celebrations and Reflections. Students can keep these pages in their binder or a folder for easy reference.
Feel free to edit the wording if you'd like to help fit the needs of your class. However, the language "I realized" and "Next time I'm going to" for the reflection pages helps children to keep an assertive mindset for truly trying to make a change next time.
I hope you find it helpful!
