How did the Franks work together to create a system of learning? Why was this important to do?

In terms of education, learning, and studying, the Franks' system required everyone to pitch in and help one another. This included Anne helping her father to learn Dutch. This is important in order to keep the young people engaged with their studies.

Father and I are currently working on our family tree, and he tells me something about each person as we go along. I've begun my schoolwork. I'm working hard at French, cramming five irregular verbs into my head every day. But I've forgotten much too much of what I learned in school.

Peter has taken up his English with great reluctance. A few schoolbooks have just arrived, and I brought a large supply of notebooks, pencils, erasers and labels from home. Pim (that's our pet name for Father) wants me to help him with his Dutch lessons. I'm perfectly willing to tutor him in exchange for his assistance with French and other subjects. But he makes the most unbelievable mistakes!
