Prealgebra (with CD-ROM, Make the Grade, and InfoTra) (Available Titles CengageNOW)

With an emphasis on conceptual understanding, PREALGEBRA eases the transition from the numerical skills of arithmetic to the more abstract world of algebra. The text concentrates on conceptual understanding in place of rote application of algorithms and encourages students to "explore algebraic concepts in an informal way to build a foundation for the subsequent formal study of algebra," as recommended in the NCTM Standards.
