102 Essential Construction Math, ENGR 35

Class Syllabus


This construction math 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.


A self paced course can be started at anytime. You must complete the course within 10 weeks but you can work through the course as quickly as you like. There are no weekly goals and no interaction with other students. Work at your own pace but you must complete within 10 weeks from your first log in.

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.


Point Value By End of Week

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

Total Points


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.
