A clear, methodical approach to topics in prealgebra, with good explanations of concepts. This book includes plenty of examples and then exercises. Equation solving is started earlier and used throughout.
Geometric topics (e.g., area and perimeter) are presented throughout the text so students might actually remember them. The applications (word problems) are mostly realistic, and the applications are spread throughout the text, not isolated in a few sections.

- MyOpenMath online homework. MyOpenMath is a free online homework system, built on the open source IMathAS assessment platform. It provides randomized, algorithmically generated homework with automated grading of numerical and algebraic answers, similar to WebAssign and MyMathLab. It also provides a course management system with gradebook, file posting, discussion forums, etc. Assessment sets have been created for this textbook, which may be available for self-study by students, or can copied as a starter course shell by faculty.
MyOpenMath use is a provided free by Lumen Learning. Community support may be available through faculty support forums. For direct support, course development and support service contracts are available from Lumen.
For Washington State faculty, the WAMAP.org site also mirrors this content.
- Videos. See the comments below for details.
There is a MyOpenMath starter course that includes video lessons for each section of the text along with online homework. The solutions manual is available on the book's home page (see link above).
There is also a self-study course based on this text available on MyOpenMath for students studying on their own.
