Tell me if this sounds like you (or maybe your teen)...
You struggle with knowing where and why to use commas...
you may know something is correct (or not), but you can't or don't have time to explain why...
you wish there were a way to help your kids become foolproof proofreaders.
That's exactly why I created my Grammar Guides. I needed to teach my 13yo reluctant writer enough to help her recognize her own mistakes and feel more confident in her writing. I wanted to build up her foundation of grammatical concepts, but more than that, I wanted her to feel empowered to apply those concepts to future writing efforts.
