This annotated bibliography identifies English language resources endorsed by all Western Canadian Protocol (WCP) jurisdictions implementing The Common Curriculum Framework for K-12 Mathematics Grade 10 to Grade 12. Resources in this annotated bibliography were selected through a collaborative review process based on their high level of fidelity with the rationale, philosophy, mathematical processes and outcomes of the Common Curriculum Framework. Resources underwent an intensive review and were found to be the most suitable of those submitted. During this review breadth, breadth and depth, depth, and teacher resources were identified for Pure Mathematics 10, 11, and 12, while depth and teacher resources were identified for selected parts of Applied Mathematics 10, 11, and 12. WCP Key Resources are high quality learning and teaching resources that best address the philosophy and content of the outcomes embodied in the Common Curriculum Framework. These include resources in a variety of media and formats with the following characteristics: (1) Breadth identifies learning resources with the highest possible level of fidelity to the general and specific outcomes published for a course; (2) Depth identifies learning resources that address a limited range of general and specific outcomes for a cluster or set of clusters but provide an especially effective learning experience for students; (3) Breadth and Depth identify comprehensive learning resources that provide both the breadth and depth dimensions for a particular course; and (4) Teacher Identified resources are those that assist teachers in the implementation of the Common Curriculum Framework and any courses derived from it. Each annotation includes series and title, resource designation, format, alternate format(s), cluster(s) grid, annotation, comments, cautions, system requirements, audience, course(s) grid, mathematical process(es) grid, and strand(s)/substrand(s) grid.
