At Mosdos Press, we believe that a workbook exercise should be fun to do. Our tools include funny characters, challenging puzzles, interesting stories, nonsense rhymes, and a host of other inventive and innovative teaching techniques. Our selection tests ensure that the students have comprehended the stories in the textbook. Our two vocabulary exercises teach definitions of words, their proper usage, and, sometimes, etymology. The MAS writing activity gives students the opportunity to respond creatively to one aspect of each story. Book One is part of the title and does not indicate more than one edition.
