This is a graphic organizer (Blank Word Formation Sheet) for my intermediate vocabulary students. They can download it as a Word Document (under the File menu) and type in different word forms along with an example sentence for any target vocabulary. Teachers can also fill in the sheet themselves, print it out, and refer students in the future to this page to download additional sheets. (If you're like me, I'm trying to save myself having to print out lots of copies for every student that loses his/her original copy or wants additional copies to add to.)
I also teach my students how to use index cards for reviewing vocabulary, but the word formation sheets are another way to review language, especially for exams which focus on being able to transform words into their correct parts of speech.
