This week marks the 50th anniversary of the March on Washington. Over the past year, I had the great pleasure of being part of a group of teachers put together by the Shanker Institute who met with participants and historians in order to plan lessons to help students think about the impact of the March, and how its memory has shifted over time. The lesson are available here for free. My lesson, which is probably worth looking through for most adults as well, looks at how popular memory has failed to capture key components and emphasis of the march.
