The Fundamentals of Grammar Workbook for Introductory Spanish, Third Edition, are exercises and explanations dealing with grammar points students encounter in first-year Spanish. The text provides students with easy-to-read explanations of the grammar point in question, followed immediately by exercises that move from easy to challenging. Each chapter has review sections which could be used as tools to the mastery of the subject. An answer key is provided in the back so students can check their own progress. This text could be used as a supplement to any first-year course, and the exercises in this workbook could be assigned as class work or for individual practice outside of class. It could also serve as a review of the material or for users to work at their own pace.
