OK, here’s a quick weekly text, starting with a context clues worksheet on the noun triskaidedaphobia. This might well serve as a template for the context clues worksheet in general–you will notice, as your students probably will, that this word means fear of the number 13. I believe the context for inferring meaning is fairly strong in these sentences.
This might also be a good time to use this worksheet on the Greek word root phobia, the utility of which I expect is obvious. This root shows up in so many words in English that knowledge of it is nothing short of de rigeur.
Addendum, May 28, 2019. Here is a comprehensive list of phobias from the pages of the Oxford Dictionary of Psychology (New York: Oxford University Press, 2003) that might interest your students; kids to tend to find this kind of thing fascinating.
