This is a very casual "how-to" guide for homeschooling in style of Charlotte Mason. The author gives short tips or recommendations for each of the following areas: Narration, Literature, Poetry, Composition, Handwriting, Spelling, Foreign Language, Grammar, Science, Math, Art, Music, Handicrafts, Bible, History, Geography, Citizenship and Morals, and The Formation of Habit.
Some of the chapters are more useful than others, as are some of the tips. I'm sure most will roll their eyes at the author's prudishness (she mentions how doesn't let her children read Dickens because she doesn't allow ghost stories in her home, plus she places sticky notes over works of art that show any nudity). She certainly strives to be devout :).
All in all, there are definitely better books out there if you are looking for an introduction to Charlotte Mason and you don't want to read a giant volume of Mason's own work. I would definitely recommend For the Children's Sake over this one. On the other hand, you may find a few good tips in here. Plus, it is only about 80 small pages, so you can read it through in an hour. (I really liked the spelling tip: Write a word on the board and let the children look at it. When they think they are ready, erase the word and then let them try writing it out. Much quicker way to learn than having them spell aloud.)
And, it did contain this gem from Charlotte Mason: "The mother who takes pains to endow her children with good habits secures for herself smooth and easy days; while she who lets their habits take care of themselves has a weary life of endless friction with the children. All day she is crying out, 'Do this!' and they do it not; 'Do that!' and they do the other." Now if only I had the perfect formula for teaching good habits...
