This document is intended as a teacher's guide to the three course options open to 10th-grade students in Manitoba. The material opens with an overview, which, after an introduction, looks at the structure for senior high school mathematics, a description of senior high courses, the use of mathematics, the general goal, objectives for 7th through 9th grade mathematics, and objectives for the 10th grade options. The next section ("Implementation") discusses a rationale; general goals for 04, 01, and 00 mathematics; the guide's sequencing and time allotments; the role of textbooks; recommended uses of calculators and computers; evaluation; special needs students; and implementation. The bulk of the document looks at the three 10th grade courses. Each section detailing individual grade 10 offerings discusses general goals, the type of student taking the course, course features, structure, and core and optional topics. The objectives and notes to teachers are presented in detail. (MP)
