## Mathematics at Work 12

### Course Outline

Mathematics at Work 12 is a graduation level high school mathematics course. Students will explore the following topics:

• Measurement
• Geometry
• Number
• Algebra
• Statistics
• Probability

#### Measurement (M):

Students will be expected to develop spatial sense through direct and indirect measurement.

• Demonstrate an understanding of the limitations of measuring instruments, including precision, accuracy, uncertainty, and tolerance, and to solve problems.

#### Geometry (G):

Students will be expected to develop spatial sense.

• Solve problems by using the sine law and cosine law, excluding the ambiguous case.
• Solve problems that involve triangles, quadrilaterals, and regular polygons.
• Demonstrate an understanding of transformations on a 2-D shape or a 3-D object, including translations, rotations, reflections, and dilations.

#### Number (N):

Students will be expected to develop number sense and critical-thinking skills.

• Analyze puzzles and games that involve logical reasoning, using problem-solving strategies.
• Solve problems that involve the acquisition of a vehicle by buying, leasing, and leasing to buy.
• Critique the viability of small business options by considering expenses, sales, and profit or loss.
• Identify expenses in operating a small business.

#### Algebra (A):

Students will be expected to develop algebraic reasoning.

• Demonstrate an understanding of linear relations by:
- recognizing patterns and trends,
- graphing,
- creating tables of values,
- writing equations,
- interpolating and extrapolating,
- solving problems.

#### Statistics (S):

Students will be expected to develop statistical reasoning.

• Solve problems that involve measures of central tendency, including mean, median, mode, weighted mean, and trimmed mean.
• Analyze and describe percentiles

#### Probability (P):

Students will be expected to develop critical-thinking skills related to uncertainty.

• analyze and interpret problems that involve probability.
