I use SWB's The Well-Trained Mind and also First Language Lessons by Jessie Wise. Will this book duplicate what I am already doing? Also, what does the workbook contain? Would you recommend purchasing the workbook along with the main book?
The workbook provides the exercises you would otherwise need to cull from your child's literature or other curriculum. It's much easier, much more "open and go." The WWE program is the writing component of English--First Language Lessons is the grammar component. TWTM is the text that describes the curricula choices recommended by Wise-Bauer and how to implement them. There is slight overlap, but only in philosophy. Each stand alone. HTH
