This open source textbook is now in its third edition with expanded topics and an interactive online (HTML) version that includes WebWork exercises (ungraded) for immediate feedback to students. The text grew out of a discrete mathematics course at the University of Northern Colorado in a discrete mathematics course taken primarily by math majors, many of whom plan to become secondary teachers. This text can also be used in a bridge course or introduction to proofs. The major topics are introduced with Investigate! activities designed to get students more actively involved and which are suitable for inquiry based learning.
