Grace,
I’m sorry it took me a bit to respond. I hope you had a restful, peace-filled holiday. I prefer Hearing and Reading, Telling and Writing, when I want to dig into how Charlotte taught composition. The handbooks covers language arts in Charlotte’s method. Charlotte utilized narration, read alouds, great literature read, copywork, as well as dictation to help children hear and see good writing.
I also have a fondness for Your Questions Answered: Narration. It includes quite a bit on the subject of written narration as well as writing samples (Hearing and Telling does as well) and raising the bar (similar to the post I linked above). The overall focus is narration rather than Language Arts as a whole.
We have an entire Narration Q & A series available on our blog. Much of that series made its way into Your Questions Answered: Narration. The two resources (Hearing and Reading, Telling and Writing and Your Questions Answered: Narration) combined make an excellent resource for families to better understand narration and Charlotte’s integrated approach to language arts.
