Get help with Mathematics 10-3
Most tutoring makes you sit through material you already know. MapleMind flips that: pick the exact skill that's causing trouble — any of the 22 below — and the tutor teaches just that one, step by step, as many times as it takes. Ask questions in plain words, any time of day, in English, French, or 12 other languages.
The official Alberta Mathematics 10-3 curriculum
Alberta defines Mathematics 10-3 by strands and outcomes. MapleMind teaches the same curriculum reorganized for one-skill-at-a-time tutoring — the table shows exactly where every official strand lands, and the ministry's own wording is quoted under each unit below.

How MapleMind teaches Mathematics 10-3 — every unit, lesson, and skill
Every skill below runs as a short session: a plain-words lesson, a worked example, solving it together, then a five-question skill check that earns up to three stars. Guided Mode keeps it teaching instead of answer-handing — turning it off needs a parent's password.
Unit 1MeasurementOfficial strand · Measurement
General outcome: develop spatial sense through direct and indirect measurement on the job. The SI (metric) and imperial systems and the strategies that convert between them, linear measurement in decimal and fractional units, and area of regular, composite and irregular 2-D shapes and 3-D objects — always in trades and workplace contexts.
The SI and Imperial Systems
- Describing the SI (metric) units10-3.M.1 — Describe how the SI (metric) units for length, area, volume, capacity, mass and temperature relate to one another — the base units and the powers-of-ten steps between them.
- Converting SI units to imperial10-3.M.1 — Apply strategies to convert SI units to imperial units on the job — multiply by a conversion factor so units cancel, e.g. metres to feet or kilograms to pounds.
- Describing and comparing imperial units10-3.M.2 — Describe how the imperial units for length, capacity and mass relate, and compare the American and British imperial units for capacity (the US gallon vs the larger British gallon).
- Converting imperial units to SI10-3.M.2 — Apply strategies to convert imperial units to SI units — turn feet and inches into metres, or gallons into litres, being careful which gallon a spec means.
Linear and Area Measurement on the Job
- Solving linear measurement problems10-3.M.3 — Solve and verify linear-measurement problems in SI and imperial units, working with decimal and fractional measurements from tapes, rulers and dimensioned drawings.
- Area of regular 2-D shapes and 3-D objects10-3.M.4 — Find and verify the area of regular 2-D shapes (rectangles, triangles, circles) and the surface area of 3-D objects for flooring, paint and material estimates, in SI and imperial units.
- Area of composite and irregular shapes10-3.M.4 — Find and verify the area of composite and irregular 2-D shapes by decomposing them into regular pieces — L-shaped rooms, cut-outs and job sites.

Unit 2GeometryOfficial strand · Geometry
General outcome: develop spatial sense through workplace geometry. Angles (drawing, replicating, constructing, bisecting) and the pairs formed by parallel, perpendicular and transversal lines; the Pythagorean theorem and right-triangle trigonometry for ramps, framing and layout; similarity of polygons; and spatial puzzles that build problem-solving strategy.
Angles, Parallel and Perpendicular Lines
- Drawing, replicating and constructing angles10-3.G.6 — Classify acute, right, obtuse, straight and reflex angles by size, and draw, replicate and construct them with a protractor, compass and framing square for a layout.
- Bisecting angles and solving problems10-3.G.6 — Bisect an angle by swinging equal arcs from each side to a crossing point, and solve layout problems that use drawn, replicated or bisected angles.
- Angles from parallel, perpendicular and transversal lines10-3.G.5 — Solve workplace problems involving parallel, perpendicular and transversal lines and the pairs of angles formed between them (corresponding, alternate, co-interior).
Right Triangles, Similarity and Trigonometry
- Identifying right triangles and verifying the theorem10-3.G.2 — Identify situations on the job that involve right triangles (bracing, the 3-4-5 squaring rule) and verify the Pythagorean formula $a^2 + b^2 = c^2$ by measurement or area.
- Applying the Pythagorean theorem10-3.G.2 — Apply the Pythagorean formula to solve problems — find a missing leg or the hypotenuse of a right triangle for a brace, diagonal or rafter length.
- Similarity of convex polygons10-3.G.3 — Demonstrate an understanding of similarity of convex polygons — including regular and irregular polygons — using equal angles and proportional sides to scale plans and templates.
- Developing the trig ratios from similar triangles10-3.G.4 — Apply similarity to right triangles and generalize the pattern that the side ratios depend only on the angle — the idea that defines the primary trigonometric ratios (sine, cosine, tangent).
- Applying the primary trigonometric ratios10-3.G.4 — Apply the primary trigonometric ratios (SOH-CAH-TOA) to solve ramp-slope, roof-pitch and layout problems, using an inverse ratio to find an unknown angle.
Puzzles and Games with Spatial Reasoning
