Crossword puzzles are an excellent, self-correcting learning tool for any subject, BUT they take an enormous amount of time to prepare. It is rarely easy to find pre-made puzzles for your particular topic. Therefore as a retirement and anti-alzheimers activity I prepared several crossword puzzles on various topics. They come with a word list and answers. They can be modified for differing competency levels and grade levels by several methods. They include allowing students to work with a partner, providing the word list to work from, starting with one or two free answers that you put in before copying or during your lesson introduction, and by providing or not providing references for use in finding answers. Maps of US rivers are available online which can be provided. Advanced students could be allowed to go to the library and search for the answers in reference books which they must locate on their own.
