May I also suggest your consideration of having service learning projects for your K-3 students. Developing and facilitating Youth Leadership with 3rd-5th grade students at Cherokee Point Elementary (inner-city San Diego) in the school-year long after school youth leadership, they chose service learning projects with a specific aim on social justice. This video clip highlights the Domestic Violence and Gang Violence groups.

My sense is your kindergarten students can still be engaged in service learning through age-appropriate dialog on how they can share their hearts and voice on behalf of others. Service learning is such a powerful practice of building empathy muscles, which build resilience. Strengthening their interpersonal intelligence, they also improve their intrapersonal intelligence.
