Morphology Book 2 is intended to be used after Book 1. The essential foundation of the morphological approach to language instruction is covered in Book 1. Book 2 completes the basic spelling rules and introduces parts of speech to cover more advanced vocabulary and reading level. Assuming Book 1 has been completed successfully, Book 2 may be appropriate for 5th grade students who are working on grade level through adult ESL students. See the posted table of contents for an overview.
