Problem Solving, Decision Making, and Integration
Students will apply algebraic, geometric, and statistical concepts and the relationships among them to solve problems, model relations, and make decisions using data and situations within and outside of mathematics. To accomplish this goal, students will develop and enhance a repertoire of skills and strategies for solving a variety of problem types. The major goal of the mathematics performance expectations is for students to become competent mathematical problem solvers in contexts found in higher education coursework and postsecondary career or technical training.

The student will solve practical problems involving rational numbers (including numbers in scientific notation), percents, ratios, and proportions.

The student will use pictorial representations, including computer software, constructions, and coordinate methods, and transformation.
This will include
a) investigating and using formulas for finding distance, midpoint, and slope;
b) applying slope to verify and determine whether lines are parallel or perpendicular;
c) investigating symmetry and determining whether a figure is symmetric with respect to a line or a point; and
d) determining whether a figure has been translated, reflected, rotated, or dilated, using coordinate methods.

The student will use similar geometric objects in two or threedimensions to
a) compare ratios between side lengths, perimeters, areas, and volumes;
b) determine how changes in one or more dimensions of an object affect area and/or volume of the object;
c) determine how changes in area and/or volume of an object affect one or more dimensions of the object; and
d) solve realworld problems about similar geometric objects.
