According to the descriptions on lulu.com, Level 1 is for grades 1 or 2, Level 2 is for grades 2 or 3, and Level 3 is for grades 3 or 4. If I decide to use Level 3, .it will be with a 5th grader, but it doesn’t seem too easy for him.
I think each lesson is supposed to be one day (3 lessons per week), but I can see how they could be broken up somewhat. The lessons that have both copywork and dictation, for example.
HTH,
