Trade Mathematics Course 2026

This course is for apprentices, trades helpers and anyone preparing for trade school or a trades exam. Six lessons cover fractions and the tape measure, conversions and scale drawings, area and volume, ratios and percentages, right triangles and trigonometry, and estimating materials and costs, with worked examples from construction, electrical, plumbing, carpentry and welding. Each lesson has an untimed topic quiz, and a timed final assessment unlocks a Certificate of Completion when you score 80% or more.

考前须知

The Government of Canada's Skills for Success model defines numeracy as the ability to find, understand, use and report mathematical information in words, numbers, symbols and graphics.
Numeracy is one of nine Skills for Success. The model describes five numeracy proficiency levels; at the highest level, tasks have several steps and numbers may need to be derived or estimated.
Under the Weights and Measures Act, all units of measurement used in Canada are based on the International System of Units (SI).
The Act defines the yard as exactly 0.9144 metre and the inch as 1/36 of a yard, so 1 inch is exactly 25.4 mm.
The Act defines the Canadian gallon as 0.00454609 cubic metre (4.54609 L) and the pound as 0.45359237 kilogram.
Red Seal exam questions are multiple choice with four choices and one correct answer, and the pass mark is 70%.
The Red Seal exam guide advises candidates to know the math concepts used in their trade and to estimate the answer to a calculation question first.
The Canada Revenue Agency lists the GST rate in Alberta as 5%, with no provincial sales tax.

常见问题

What is the Certificate of Completion, and what is it not?

It shows that you finished this course and scored at least 80% on the final assessment. It is not an accredited qualification, a Red Seal or apprenticeship credential, or a government, employer or vendor certification.

Will this course prepare me for the Red Seal exam?

It practises the general math that many trades use, which can help. The Red Seal exam also tests the full knowledge of your trade, so study your trade's occupational standard and official Red Seal preparation materials too.

Does the course use metric or imperial units?

Both, because Canadian job sites use both. Lesson 2 shows how to convert between them using the exact definitions in the Weights and Measures Act.

Can I use a calculator?

Yes. Most questions are easier with a calculator, and the trigonometry questions need one set to degrees. Estimate the answer first so you can spot a slip.

How does the final assessment work?

It has 35 questions drawn at random from the course question bank, with a 35-minute time limit. You need 80% to pass, and each attempt gives a new mix of questions.

这份证书是否经过认证或获得官方认可？

不是。这是一份私人颁发的结业证书，仅用于知识学习。它未获得任何政府、执照发放机构、监管机构或教育机构的认可、认证或批准，也不能替代法律要求的任何执照、资格证书或培训。
