OK, last but not least on this summer afternoon, here is a worksheet on the Greek word root apo–. It means away, from, off, and separate.
I don’t know if I’ve ever used this document in the classroom, which isn’t surprising, since I have hundreds of these worksheets. I tend to use the most productive roots, with words that students must use to navigate the secondary common branch curricula, in my weekly instructional period dedicated to word roots and vocabulary. Still, you’ll find this root at the basis of apogee, apology, apostle, and apostrophe among other relatively high frequency words in English, so it might be worth asking students to take a look at it. I think I would be inclined to modify it into a shorter, simpler pattern recognition exercise. Because this is a Microsoft Word document, you too can manipulate it to your purposes.
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.
