The curriculum has Kindergarten to Grade 7 learning outcomes have been arranged according to the following four been adapted from the Common Curriculum curriculum organizers: Framework to meet the needs of British • Number • Patterns and Relations • Shape and Space • Statistics and Probability The Mathematics K to 12 curriculum reflects that mathematics is a common human activity, becoming more important in our increasingly technological society. A greater proficiency in mathematics will increase opportunities available to the students of British Columbia. The learning outcomes of the Mathematics K to 12 curriculum were developed as part of the Western Canadian Protocol for Collaboration in Basic Education. They represent the combined efforts and talents of British Columbia educators and education partners and those of the provinces of Alberta, Saskatchewan, and Manitoba, as well as the Yukon Territory and Northwest Territories. These learning outcomes form the Common Curriculum Framework for K to 12 Mathematics for Western Canada. Columbians. There is an increased emphasis on the applications of mathematics, problem solving in real world contexts, and the use of technology in learning and doing mathematics. Opportunities to meet the prescribed learning outcomes must be equally available to male and female students. The Integrated Resource Package (IRP), available in April 1995, will offer gender-sensitive strategies to ensure that girls and boys are equally attracted to mathematics. The learning outcomes for Mathematics K to 7 are arranged according to four curriculum organizers. In the Number organizer, the student uses numbers to describe and represent quantities in multiple ways. The student also develops understanding of and proficiency in arithmetic operations and uses calculations to solve problems. The Patterns and Relations organizer focuses on the use of patterns to allow students to solve problems and describe the world around them. In Grades 6 and 7 the concept of patterns is expanded where the student represents algebraic Mathematics 8 to 12 The Mathematics 8 to 12 curriculum will build on the K to 7 curriculum. The curriculum is intended to prepare students to meet the challenges of a changing workplace by providing them with the mathematical, problem solving, and technological skills, depending upon their personal, education, and career goals. expressions in a variety of ways. In the Shape and Space organizer the student uses measurement to describe and compare real-world phenomena as well as describing the characteristics and relationships of three-dimensional objects and two-dimensional shapes. In the Statistics and Probability organizer, learning centres around collecting and analyzing data to make predictions and draw conclusions.
