This document outlines principles from the 7 Habits of Happy Kids and Montessori's Grace and Courtesy lessons to establish a framework for improving school culture. It discusses establishing habits through daily lessons and practices over 21 days. Each habit is defined and age-appropriate activities are provided to teach proactivity, putting first things first, win-win resolutions, empathy, teamwork and self-care. A weekly Lunch and Learn session is proposed to reinforce the lessons through stories, role-playing and reflection.
