This has been the only grammar curriculum that I've found that takes it step-by-step in easy to understand format. I've tried other popular curricular that ended up frustrating me and my kids. The lessons are short, easy to follow, and each builds on the other. We love it.
Basic Winston Grammar is easy to teach and easily learned. The teacher book is short and to the point and explains what to emphasize in your teaching. The way the worksheets are set up with the cards makes it so easy for the kids to learn, no matter what kind of learner they are. The visual cues on the cards are priceless. My kids really learned their grammar quickly and easily when they started using Winston Grammar.
This program is one of the best I've used and I've used quite a few homeschooling grammar programs. It covers all learning modalities--visual, auditory, and kinesthetic. My daughter learned grammar through this program when she couldn't get it any other way. It is excellent!!
This program is excellent! If your child needs help visualizing how things are put together this program's card system will help. Also, the cards have helpful hints printed on them that will help your child identify different parts of speech. These hints are short and easy to remember, so that if you are without the cards you can remember what to do. I like this program because it seems to address all types of learners well.
