When teachers name the texts
they like best for teaching discrete mathematics, there are four
titles that are mentioned over and over.
In roughly descending order of popularity,
the texts are as follows: *Mathematics,
a Human Endeavor*; *For All Practical Purposes*; *
Excursions in Modern Mathematics*; and
*Discrete Mathematics through
Applications*. These have been used not only as texts
for discrete mathematics courses, but as supplementary reading
for teachers who are introducing discrete topics in
traditional courses.
In the remainder of this section we give further details on content,
describe how teachers have used the books, and give teachers' comments.

There are also several mathematics
curriculum development projects at the high school
level which contain many discrete topics. One is the NSF-funded
Core-Plus Mathematics Project, which is discussed in [15]; these
materials are being published under the title *Contemporary
Mathematics in Context* by Everyday Learning Corporation. Another is
the NSF-funded ARISE project, being developed by the Consortium for
Mathematics and its Applications (COMAP); these materials are being
published under the title *Mathematics: Modeling Our World* by
South-Western Educational Publishing Company.
