Especially recommend the Noden and the Schuster. They help you teach real writing, not just filling out worksheets. The last one helps you grade real writing. Great books for new and veteran teachers. IMAGE GRAMMAR really helped me revamp my entire teaching paradigm. I finally understood how backwards my methods were and why my students couldn’t translate grammatical knowledge into decent writing. IG changed all that and now my TAKS scores have increased 3 years running. But more important than that, my students develop writing style.
