I am using ELTL for language arts this year. I’m subbing in Spelling Wisdom since we prefer the dictation selections there, but I really like ELTL’s approach to writing. She breaks down written narrations into simple steps. It is a Classical/CM approach, so it has a bit more writing than just narrations. She gets into outlines and literary analysis as well.
I do plan on teaching essays and research papers before they graduate, but I’ll wait until high school for those topics. We have also played around with this book: http://www.learn4yourlife.com/Write-On.html . While it’s not purely CM, I have found it fun and easy for the kids to use. We have been doing 1 assignment per week from it this year.
Another suggestion is to have them type their narrations. My DC prefer this over writing them by hand. I hope to have them able to do both eventually, but for now I’m just glad they are putting their ideas into words.
