Alberta Grade 11 Mathematics 20-3 Overview
Mathematics 20-3 is an Alberta Grade 11 course designed to build practical math skills students can apply in everyday life and trades. The course spans measurement, geometry, trigonometry, 3-D representations, personal finance, and algebraic formula use. StudyPug covers every unit so Alberta students always have support when they need it.
Measurement and Geometry
Students in Mathematics 20-3 explore surface area and volume of 3-D objects including spheres and composite shapes. They estimate using referents, convert between SI and imperial units, and investigate what happens to surface area and volume when dimensions change. These skills are directly useful in trades and technical programs.
Trigonometry and Scale
The trigonometry unit focuses on right triangles, angles of elevation and depression, and real-world contextual problems. Students learn to sketch 2-D and 3-D representations to support their solutions. The scale diagrams unit teaches students to read, construct, and draw scale diagrams with and without technology — a key skill in design, construction, and drafting.
3-D Representations and Exploded Diagrams
Students draw top, front, and side views of 3-D objects and use isometric dot paper to represent them accurately. The exploded diagrams unit teaches students to break apart objects into components, draw them to scale, and reconstruct 3-D objects from their parts — skills valued in technical and vocational fields.
Personal Finance
- Create and adjust personal budgets based on income and expenses
- Solve problems involving simple and compound interest
- Use the Rule of 72 to estimate investment doubling time
- Compare banking account types and understand ATM and online banking
- Evaluate credit options including credit cards, loans, and sales promotions
Formula Application and Slope
Students apply and manipulate formulas used in trades and occupations, then verify their equivalence. The slope unit connects mathematical slope to real-world contexts like ramps, roads, and roofs, and explores the relationship between slope and angle of elevation. Students solve contextual problems involving slope and rate of change throughout this unit.
