If you can use it, and there are related materials elsewhere on this blog, here is a Cultural Literacy worksheet on the Black Power Movement. This is a full-page document with a reading of four sentences (the last one a long compound separated by a colon) and five comprehension questions.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
