For each chapter of Ecce Romani I, I would hand out a derivative worksheet to the students. Each student was assigned 1-2 words, depending upon the class size. The student was responsible for carrying out the directions for those words: Write down the Latin root word and its meaning, the part(s) of speech, and definitions(s) for the derivatives listed below; then write a sentence which exhibits proper usage of the derivative word. The next day the students would stand in the front of the classroom and give their information to the other students, who would in turn copy down all but the provided sentences. The students thoroughly enjoyed this activity, as they were encouraged to create humorous and/or memorable sentences. I also had derivative PowerPoint slideshows (already online at this site) to use as a review before chapter quizzes.
