I am a fan of Wordly Wise 3000 vocabulary books! I like the variety of exercises for each lesson, and the fact that definitions are given for the verb form of a word as well as for its adjective form. My children enjoy Wordly Wise 3000 overall. Each word list has 5 exercises following it. I have my son combine exercises B and C so that he can split exercise E over two days. (Exercise E involves reading a passage and answering 15 questions about it using complete sentences.) I do not use the teacher's guide or the tests, so I am not familiar with those.
