This resource publication is primarily intended to aid elementary teachers in bringing each of their students to a higher level of mathematical competency. While the material has been designed for use in grades K-8, parts are considered appropriate for basic skills reinforcement at the secondary level. The document opens with a review of current developments and possible directions in mathematics education, and incorporates lengthy abstracts from the National Council of Supervisors of Mathematics (NCSM) "Position Paper on Basic Mathematical Skills." The bulk of this work consists of: (1) individual chapters devoted to appropriate teaching activities for grades K-3; (2) combined chapters for grades 4-6 and for grades 7-8; (3) a listing of resources that includes books arranged alphabetically by author, a list of publishers, and directories of periodicals and special resources; and (4) a reader evaluation form for the document. Each chapter on activities opens with an index list of behavioral objectives, and the content pairs each stated objective with detailed information on how to conduct a corresponding class activity.
