Noted beneficial boards to support annual celebrations in education

I was happy to read in posts, those having found Rev. Dr. Martin Luther King Jr. material that can be expanded in the classroom. I attended the recent celebration in my area, with our Associate Superintendent acknowledging educator efforts, (Art specifically, for which my student had won the yr. prior), to build community in the growing participation in the Art contest, and related community building events. I'd love to start content in the future presenting with the use of Pinterest for such themes/ lessons.
