Grammar

Wait until the child is at least 10 yrs old and he has practice with narration before beginning grammar. Simply Grammar by Karen Andreola is a summary of all CM's writings on grammar which are spread throughout the series. The book teaches one concept at a time.

Sit on the couch for 15 minutes and go through the book orally together.
