Grammarics is a great site that creates pictorial representations of grammar rules to help kids (& adults) learn correct grammar. I was given a free copy of their educational e-book (vol.1) to review and share here with my readers. They have also kindly offered to give away 5 copies of the e-book to you guys!
On their site they sell e-books, and posters to use in teaching. These would be great in a homeschool or classroom setting to help your kids with their grammar. The pictures they have created are so much fun to read through. My son really enjoyed them and I loved seeing him giggle over the mistakes. Pictures are always a wonderful way to teach a concept. It really helps solidify it in your mind! This e-book covers 42 concepts on grammar, punctuation, and word usage that are common mistakes in the English language.
