Peek Inside

I'm not struggling as much when I write. My sentence structure makes more sense.

Elizabeth O'Brien makes grammar fun. I've always like the ins and outs of grammar, but Elizabeth really breaks it down in a logical and totally understandable way. 

I've used her materials to work on grammar with my clients who have dyslexia and autism. I can't imagine teaching grammar without her Sentence Diagramming Reference Manual. I recommend it to all of my teacher friends and to home-schooling families.

Sentence diagramming is a fabulous (and fun) way to teach or learn grammar. Once you start to view sentences in a different way, you will never again confuse adjectives and adverbs, you will recognize prepositions and have the fun of "solving" diagramming puzzles. 

For both students and teachers, this book is an essential reference. It is definitely designed to be strictly a reference and it is arranged alphabetically.
