Learning by the Moore method - Books for self-study I recently read about the Moore method for learning mathematics (Moore method Wikipedia) and wanted to apply it to my own learning (undergraduate level). However, I am unable to find any books that follow such a method or something similar.
Specifically, I'm looking for books that introduce the reader to important mathematical concepts through problems/questions rather than blocks of text (for instance, instead of the book proving Lagrange's theorem in group theory, the reader is presented with a question which guides the reader by introducing the definition of cosets etc., so that the reader can prove it themself). I am not very picky about the topic, for I have not been able to find such books on any topic so far. Any recommendations? Thanks.  

Coursera has a course called Introduction to mathematical thinking by Stanford math professor Keith Devlin. He has a book by the same name you can buy it on Abebooks.com, it's print to order for about 12 bucks. Or you can audit the course for free. As an introduction they have a video on inquiry-based learning which is similar to the Moore method but not completely. Video Creativity in Mathematics and the Moore method
