PRACTICE ASSESSMENT
Grade 9 Math
- Apply the mathematical processes (problem solving, reasoning, reflecting, connecting, communicating) throughout learning in strands B through F.
- Develop conceptual understanding and procedural fluency across all strands.
- Make connections between mathematics and lived experiences, various knowledge systems, and real-life applications.
- Relate mathematical thinking to employment and career contexts, including pathways toward IB Diploma studies.
- Make connections among various number systems and the cultural development of number concepts.
- Extend operations with positive fractions and positive decimal numbers to include negative fractions and negative decimal numbers.
- Perform operations with integers, negative fractions, and negative decimal numbers.
- Extend knowledge of percentages, ratios, rates, and proportions to solve real-life problems.
- Build fluency with rational number operations required for IB DP Mathematics coursework.
- Generalize relationships between algebra and numbers using algebraic expressions and equations.
- Extend and apply coding skills to dynamically represent situations, analyse concepts, and solve problems.
- Represent linear and non-linear relations using multiple representations (tables, graphs, equations).
- Determine the constant rate of change and initial value of linear relations.
- Solve real-life problems related to linear relations, laying groundwork for IB function and equation work.
- Examine the collection, representation, and use of data, including its implications in various contexts.
- Consolidate and extend understanding of data involving one and two variables.
- Connect data analysis to real-life situations.
- Apply the process of mathematical modelling to analyse real-life situations using data.
- Build statistical reasoning skills that anticipate IB DP Mathematics statistics topics.
- Make connections among geometric properties and their real-life applications.
- Analyse and create designs involving circle and triangle properties.
- Solve problems using different units within and between measurement systems.
- Examine relationships between the volume of cones and cylinders, and of pyramids and prisms.
- Solve problems involving perimeter, area, surface area, and volume.
- Analyse financial situations to explain how mathematics can inform financial decisions.
- Explain appreciation and depreciation, and how budgets can be modified based on changes in circumstances.
- Compare the effects of different interest rates, down payments, and other factors associated with purchasing goods and services.
- Apply learning from other strands to solve financial problems of interest.
- Introduce function notation and evaluate functions for given inputs, extending Strand C algebra skills.
- Graph and interpret quadratic relations, identifying vertex, roots, and direction of opening.
- Preview right-angle trigonometry (sine, cosine, tangent) to extend Strand E geometry skills.
- Prepare foundational skills required for Pre-IB Grade 10 Mathematics and eventual IB DP coursework.
