*Mathematics, A Human Endeavor* was clearly a textbook ahead of its time.
After going through its third revision in 1994, it is as popular today as a
classroom text and a teacher resource as it was back in the late 60s.
It is a recommended favorite of teachers in the Leadership
Program in Discrete Mathematics. Much of the
mathematics is connected to
real world applications, and there are many science and mathematics
connections.
The book is jammed with problem-solving activities and ``What if
...?'' questions, and emphasizes mathematical thinking. It is also full
of photos, drawings (e.g., from Escher), and
mathematical cartoons (e.g., from *Peanuts*, *BC*, and
*The New Yorker*). The following background is adapted from
information provided to us by the publisher:

In the late 1960s, Harold Jacobs, teaching at Grant High School in Southern California, began exploring various mathematical applications for use in the classroom. He decided to write a textbook, something original, for those students who had not done well in mathematics. Neither the author or the publisher anticipated the response of instructors to the book when it was first published. Much to his surprise, Harold Jacobs found that he had taken the mathematical community by storm. And the author is still teaching students and finding ways to introduce them to the beauty of mathematics--to motivate them to see beyond its apparent difficulty. (W. H. Freeman, private communication.)

- inductive and deductive reasoning;
- patterns and sequences (e.g., Fibonacci numbers);
- symmetry and regular polygons;
- combinations, permutations, and Pascal's triangle;
- probability and statistics;
- logic and puzzles;
- network (graph) problems--including Euler paths and trees.

I've been using this book for over 20 years. I've used it for a senior elective for college-bound students who have had a rough time with the traditional SAT curriculum. I've used several topics in a general math class (inductive reasoning, sequences, combinatorics, elementary probability). I've used activities from it in traditional courses (functions, conics, logs). No matter what school I teach in, I make sure that I have a classroom set of this book. (Marilyn Goldfarb LP `93), private communication.)The following are comments from other teachers who have used this text.

- A wonderful all-around reference. Perfect for self-teaching. Good combinatorics section.
- This is my favorite math text book.
- A ``must'' for every library.
- It was written with ``people who don't like math'' in mind. It has a nice tone, develops the topics nicely, and goes into some depth.
- The supplemental transparency package is a definite ``keeper.'' The material in it is excellent.
