Neue Kommunikative Grammatik: An Intermediate Communicative Grammar Worktext with Written and Oral Practice

This book is a wonderful text on German grammatical forms. It's in-depth enough to be informative to intermediate students, yet covers the basics like definitive and infinitive articles, and noun and adjective declension for beginners (like myself). The only negative is the absence of an answer key (why 5, not 4); purportedly sold separately, though I've yet to find it.

I used this book with my third year students as a review of grammatical structures already learned and for the excellent activities. The activities were well thought out and support the prevalent theories on second language acquisition, using the communicative approach. It offers an excellent way to fine tune all grammar structures learned in a first and second year course and goes into some detail concerning the finer points of these grammar concepts, giving the interested student a challenge, if desired or needed. Subcategories are well divided so you can pick and choose which areas to highlight or to ignore, if you please. I myself have used the activities extensively and would say it is definitely a good supplemental tool for the intermediate and advanced German student. Another German teacher in my district intends to use it based on my recommendation.
