What should change about teaching Native American history in the United States?

Schools start teaching about "Native American Culture" in Kindergarten but schools don't actually inform their students on Native American culture. They only offer the bare minimum like reenacting the First Thanksgiving but shouldn't they offer more? It's important to learn and have knowledge of indigenous culture and celebrating their heritage helps grow their culture.
