I don't get the point of structuring a textbook in this way. It seems like a huge waste of time if you just want to quickly learn some stuff.
The series is written to incorporate situations which require math to arrive at a resolution, thereby helping a student to make connections so that math is relevant. The point of structuring the books this way is: as the children learn math they do not wonder, "When will we ever use this stuff?", a question which many teachers appear unable to answer.
Like any tool or curriculum, LoF works for many but may not be a good fit for all.
