10 of the albums are written to cover the start of lower elementary. This is because children that are 5 and 6 years of age often need to go further in their studies. Children seem to progress quickly in some subjects and not in others. Since, we do “follow the child” I have extended the scope of my albums to make sure that children ages 2-6 can go as far as they are capable and ready to in all of the subjects.
I also refer my students to another instructor that runs a course for lower elementary, similar to the way that I do this one…her course “bridges” my course. So, I go up beyond the typical (if there is such a thing) 6 year old, and she starts down below what a 7 year old would start.
Hope I have helped,
