One of the great things about Analytical Grammar is that you don't have to teach it all year! Instead, we recommend breaking it up over three grammar 'seasons.' Below are two timelines to illustrate this. The 36 boxes represent the average length of a school year. Each unit in the program takes about a week to do. The "Rs" refer to exercises in the Reinforcement and Review book.
Here's the unit breakdown:
Units 1-10: Parts of speech, parts of the sentence and the basics of sentence diagraming
Units 11-17: All the phrases and clauses (this completes the study of grammar)
Units 18-34: All the rules of punctuation (commas, semi-colons, colons, quotations, etc.) and usage (who or whom, I or me, etc.)
If your student begins AG in either 6th or 7th grade, we recommend using this timeline:
If your student begins AG in 8th, 9th, or 10th grade, we recommend this timeline:

If your student begins AG in 11th or 12th grade, it may be best to go through the program all in one year. In that case, you needn't order the Review and Reinforcement book.
