Grammar rules can get tricky. There seems to be as many exceptions as there are rules. It is especially difficult to follow correct grammar when we are so used to hearing it used improperly.
But as a homeschool teacher I need to be sure I'm sharp on my grammar skills so I can teach them correctly to my children. I found a website that I use to look up quick answers to my grammar questions. It is easy to use and its free!
It's called Ginger Grammar Checker and I love it! I'm just amazed that technology like this exists.
Just type your sentences into the first line and Ginger will make any corrections in the second line. It's just that easy!
Give it a try yourself. It corrects problems with subject-verb agreement, singular/plural nouns, consecutive nouns, misused words, and contextual spelling mistakes.
