Established authors Alison Warr, Cathy Curtis, and Penny Slingerland have produced class-tested first editions written to speak to the challenge of the NCTM and AMATYC Standards and technology integration in the classroom, the authors use the following means to address the standards: * Numerical, Graphical, and Algebraic Models: The exposition usually begins by synthesizing the concepts discovered in the activity sets. Concepts are presented through non trivial applications. Mathematical models are presented numerically, graphically, and algebraically with an emphasis on the connection among the three representations. * Guided Discovery Activities: Students discover concepts and strategies through guided activities. Co-operative learning teams are used to facilitate understanding and improve communication. * Problems Solving: Students are expected to communicate their ideas, processes, and understanding orally and in writing. * Collaborative Learning: The problem sets include skill building problems, conceptual questions, and appli...
