## MTH1W Mathematics

#### Open Course

Ministry of Education Course Title: Mathematics, Grade 9

Course Code: MTH1W

Prerequisite: None

Department: Mathematics

### Course Description:

This course enables students to consolidate, and continue to develop, an understanding of mathematical concepts related to number sense and operations, algebra, measurement, geometry, data, probability, and financial literacy. Students will use mathematical processes, mathematical modelling, and coding to make sense of the mathematics they are learning and to apply their understanding to culturally responsive and relevant real-world situations. Students will continue to enhance their mathematical reasoning skills, including proportional reasoning, spatial reasoning, and algebraic reasoning, as they solve problems and communicate their thinking.

### UNIT 1: Numbers – 20 hours

This unit will expand on the use of fractions, ratios, rates, proportions, and number sets, as well as introduce the rules for working with exponents. Students will also be introduced to abstract concepts like infinite sets and limits of a pattern.

### UNIT 2: Algebra and Coding – 28 hours

This unit will focus on setting the foundations for working with linear relationships. Students will investigate the properties of linear and non-linear relationships, the different representations of linear relationships, and solve theoretical and application problems involving linear relationships. The unit will also connect algebraic concepts to coding applications. Students will read and write pseudocode, making use of comparative statements and loops, that produces solutions to real-life problems.

### UNIT 3: Geometry and Measurement (20 hrs)

This unit explores a variety of measurement systems and introduces the factor label method for converting between different unit types. Students will also investigate geometric relationships such as the volume differences between pyramids and prisms as well as cones and cylinders.

### UNIT 4: Data (23 hrs)

This unit will expand on the foundations of data collection and data analysis and build toward a project where students conduct a survey and analyze their data. Students will create a mathematical model for their data and test its validity.

### UNIT 5: Financial Literacy (15 hrs)

This unit will build on the idea of compound interest and students will learn about models of appreciation and depreciation in a Canadian context. Students will also learn methods to adapt a budget so that it continues to work under moderate changes in circumstances.
