Query: Great Supplement

I purchased this as a supplemental workbook for my son's 2nd grade English homeschooling curriculum. It offers lots of practice in all topics, so I know that by the time we have completed each section, he truly understands the material. The only thing that I would change is for the book to begin with sentences instead of parts of speech, but that is just my personal preference.
