A resource for grammar

Do you have trouble with using proper grammar? Do you have problems teaching it to your children? Here is a resource that I highly recommend. She goes back to basics. she teaches diagramming step-by-step. Besides the book she also provides regular exercises and resources via email. http://www.english-grammar-revolution.com/products.html. Her products include ebooks and videos. I used this with one of my students and she was fascinated by the diagramming process. It made sentence structure logical and precise. She was an adult learner, and needed to re-take her placement test at the community college. Before we went through the course, she tested at the remedial level. A few weeks later, after practicing and studying, she tested at the honors level.  I would say that is a resounding endorsement!
