I have the Prairie Primer. It offers lots of activities and info for each book in the series.
It starts with a few pages with background into or some sort of focus for the book. For example, the Big Woods book mentions a lot about foods that were eaten and how they were prepared, so there is a focus on nutrition. In the next book, there is Background info about the Osage Indian tribe.
Then there is a planning guide for each week that gives a supply list, suggested field trips, and suggested videos. There is plenty to choose from, so you probably wouldn’t do everything, then there is a day by day guide with questions for comprehension of the reading and activities by subject (literature, science, writing, Bible, manners, etc).
I felt that it was friendly for boys or girls. I know some people worry that it would be more geared to girls, but I have 2 sons and 1 daughter and didn’t find that to be a problem.
I actually just set my copy aside to put up for sale, so if you you decide to buy it, you’re welcome to PM me if you want a used copy. It has some highlighting and underlining in the first unit because I also bought it used. It is in perfect physical condition. I’ll sell it for $15 including shipping (if you’re in the US). I also have the Little House Cookbook and Laura Ingalls Wilder Country, which I’ll be selling. I could throw those in for $5 each.
