Keys to Teaching Grammar to English Language Learners: A Practical Handbook is not intended to be an exhaustive reference book about ELL grammar. Written for classroom teachers (K-12, ESL, EFL), this book teaches the most common ELL grammar points in an accessible way through real ELL errors with suggested teaching techniques. Relevant grammar terminology is explained where practical.  The four objectives of the book are to help teachers: (1) identify common ELL grammar points and understand the details associated with each one; (2) improve their ability to answer any grammar question on the spot (when on the "hot seat"); (3) anticipate common ELL errors by grammar point, by first language, and by proficiency level; and (4) develop more effective grammar/language learning lessons.  The presentation of each of the 15 keys (grammar points) features information on typical ELL errors, an accessible grammar explanation including examples of mistakes, a native language interference chart, and ideas for teaching the grammar point.  The Workbook for Keys to Teaching Grammar to English Language Learners provides extra practice in the grammar points studied in the handbook.
