This Teacher Resource Manual (TRM) is designed to help teachers implement the Mathematics 20, 23, and 24 courses. The TRM is a support document that provides helpful information to classroom teachers. An overview of the Course of Studies for Mathematics 20/23 and 24 is provided at the beginning of each course section in the TRM. The overview includes the specific learner expectation, the attitudinal expectations and the problem-solving expectations for each course. In addition, the Mathematics 24 overview includes the specific numeration expectations. For each concept covered in every program the skills, process/problem-solving context with sample problems, elective suggestions, and resource correlation are included. Templates for a binomial grid and algebra tiles, support resources, samples of student evaluation ideas, ideas for combining writing and mathematics, guidelines for effective media integration, addresses for the Alberta Consumer and Corporate Affairs Offices, and a list of the Alberta mathematics consultants are appended.
