We usually finish the morning work by noon and take off an hour for lunch. For years we followed lunch with a reading and resting time. The older boys would read independently, and I would read aloud to the younger ones before they napped. Once the little guys were asleep I would begin afternoon school with the older ones. Now, alas, no one naps and all are full of energy after being cooped up all morning.
Lunch is followed instead with basketball.
After this the two older boys devote 90 minutes to history or science. I introduce a topic by reading a relevant selection, such as a chapter from A Child's History of the World, by Virgil Hillyer, or from Handbook of Nature Study, by Anna Comstock, followed by discussion. The boys have an hour of assigned reading on the topic of the day. While the big boys read independently, I read to the little boys. Before each six-week school period begins I have developed a syllabus of daily topics, readings, and activities.
