Estimation Exercises: Developing Skills in Accuracy and Rough Estimation, Slides of Engineering Mathematics

Learning objectives, explanations, and exercises to help students develop estimation skills. Engineers aim for high accuracy, but sometimes rough estimates are sufficient. The accuracy of estimates depends on consequences of error, available reference materials, time allotted, and experience. Students are given three estimation exercises to practice, including estimating annual revenue from student fines, converting chicken feathers into chicken feed, and calculating paint volume for a classroom.

Estimation

Learning Objectives

  • Develop estimation skills

Estimations

The accuracy of these estimates depends on:

  1. Consequences of error,
  2. Available reference materials,
  3. Time allotted for estimate,
  4. Experience with similar problems.

Estimation Exercise 1

  • Individually spend 2 minutes on the following:
    • Determine the annual revenue generated from the fines paid by students that illegally park on Gordon College campus.
  • Spend 3 minutes discussing the solution as a team

Estimation Exercise 3

  • In your team, Front pair:
    • Determine the maximum number of ping pong balls (not crushed) that could be stored in this classroom.
  • In your team, Back Pair:
    • Determine the volume of paint (gallons or liters) to apply one coat to all the painted walls in this classroom.
