Swimmy
Students in Grades 1-2 read the book Swimmy and talked about cooperation and teamwork. Each class made a fish out of individual red fish for the students and a black fish for the eye representing the teacher.
I do weekly lessons in Kindergarten and monthly lessons in 2-5 on topics such as Bucketfilling, teamwork, friendship, and dealing with anger. We have also read "The 7 Habits of Happy Kids", by Sean Covey and done lessons to work on each habit.
