$550 Member / $650 Non-member

This 10-week course can be started at any time. Once your registration is received, the instructor will be notified of your enrollment within one business day. Your textbook will be mailed to you, and by the time you receive it, you should receive login instructions by email from the instructor.

  • For US addresses, shipping will be by USPS and will take three to five days for delivery.
  • For Canadian and International Addresses, shipping can take much longer. Tracking information will be made available.   

This self-paced class is intended to develop mathematical skills that can be applied to the construction trade through practice and application. This course is an introduction to other courses in construction. While this class is not a prerequisite for any other classes, it does provide a foundation for them.

Learning Objectives
By the end of this class you should:
• be able to use and understand all operations on fractions and decimals that are common to the construction industry.
• be able to convert measurements from fractions to decimals
• be able to calculate area, and volume of various shapes
• be able to convert measurements from cubic feet to cubic yards
• be able to measure the volume of concrete footings, slabs, walls, and columns.
• be able to calculate board feet
• be able to calculate and measure for basic constructions in wood and concrete

Class Organization and Grading
For this class it is highly recommended to keep a spiral bound or similar notebook to keep all assignments and notes together. Each week you will be given a lecture, assignment, answers (from the previous assignment) and a quiz. The reading and lecture will be designed to aid in the completion of the homework.

While homework will not be checked there will be answers posted each week to self-check your progress. There will also be a quiz testing the information from the previous assignments. There will also be two projects to complete, one mid-semester and one at the end of the class. The projects are applications of mathematics to a construction problem.

The following table lists the learning modules, the maximum value in points a student can receive within each module, and the time in which the modules must be finished.
Module Point Value By End of Week
0. Student Orientation 0 Before start
1. Numbers 10 1
2. Fractions 10 2
3. Conversion 10 3
4. Using ratios 10 4
5. Angles and triangles 10 5
6. Formulas: Area and Volume 10 6
Case study 1 20 7
7. Board Measure Lumber pricing 10 7
8. Concrete 10 8
9. Walls and roofs 10 9
10. Stairs and covering 10 10
Case study 2 20 10
Final Quiz 20 10
Total Points 160
Each module should take approximately one week to complete. Course modules will be made available after the previous module’s quiz is compete. You will need to e-mail the instructor to make him aware of your progress and receive the case study quizzes.

Grading Policies
Graded assignments will consist of one quiz for each module, two case studies and a final quiz. Each quiz will count for 10 points. The case studies are each worth 20 points. The final quiz is also worth 20 points.

Grades will be posted on a weekly basis. You will have full access to your grade sheet so you will be able to keep track of how you are doing at all times.

Your overall grade in the course will be determined by the total number of points you have accumulated on quizzes and assignments. The grading scale is as follows:
  • A 144 to 160 points
  • B 128 to 143 points
  • C 112 to 127 points
  • D 96 to 111
  • Anything less will be considered either failure or an unauthorized withdrawal from the course.
You will be given more information about the grading and other course matters in the Orientation Module.

Withdrawals and Refunds
You may withdraw from this course by sending an email to or by conventional mail requesting to be dropped from the course. Non-attendance or notifying the instructor does not constitute officially dropping or withdrawing from a course. Students who stop attending courses without officially dropping will receive a grade of U in the class. Refunds are not automatic. NO refunds are due unless the course is officially dropped within stated guidelines in the refund schedule.

Refund Schedule
a. Withdrawal received before the first day of class – total fee less a $125 cancellation fee.
b. Refund requests postmarked on or after the first day and no later than two weeks after the first day of class will be refunded 65% of the fee, after which time there is no refund.
c. Decision on withdrawals and refunds will be based on the date when the written withdrawal notice is received by AACE International. Drops done by mail are effective as of the postmark date.
