Here is a Cultural Literacy worksheet on the Indian Ocean. This is a half-page document with a reading of two sentences followed by two comprehension questions. In other words, as Detective Joe Friday liked to say, grimly, on the old Dragnet series, “Just the facts, ma’am” (or sir, though in my memory he is always saying it to women, as though women need constant reminders to remain focused and rational).
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.
