How about some school spirit? For staff? For students? For families?
Put together a brief survey, use google form or survey monkey, with options for school spirit days and let students, staff, and family members vote! Top it all off with a dance as the finale! Give everyone something to look forward to, or work for! I've always heard of many "Save the Spring" efforts from administrators in my district and I agree, we need to save the spring. But I think it's more fitting to say "Have Some Fun" or "Save Our Building" or "Be Great" or something else cheesy. Inspire students, remind them that you care, create a home away from home, and more importantly have fun, get goofy with your students!
