As homeschooling mothers ourselves, we realize that homeschooling parents do not have a lot of time to prepare lessons. Therefore, the teacher’s manual is very easy to use and most of it is designed to read aloud. For the most part, you would need to look over the lesson the evening before and make sure you have the list of supplies on hand. We suggest doing a lesson once a week, and allowing about 1 1/2 to 2 hours to go through it. The older children will then continue with “Digging Deeper” ideas between lessons. This set-up makes it ideal for fathers to be involved in the homeschooling process. And since the children really enjoy the lessons, it makes for a fun, learning time with Dad, even if it has to be done on the weekend.
There are actually 36 lessons, but some of the lessons have several parts, so you might want to consider dividing these into more than one session. (For instance, all the planets are covered in one lesson, and this is definitely overload for the younger ones.) It would be no problem to take a couple of years to go through the book once, and then to repeat it when the younger children have reached a 5th or 6th grade level.
