  2. Objectives • Terminal Objective • read dimensions using a standard ruler • Performance Objective • given a diagram of a standard ruler with extension and dimension lines, read dimensions to a 16th of an inch, using proper or mixed fractions in their lowest terms, with a minimum score of 90% correct.

  3. Objectives • Enabling Objectives • define the following terms: whole numbers, proper fractions, improper fractions, mixed fractions, numerator, and denominator • identify extension lines, dimension lines, arrowheads, and dimensions • explain how to identify units on a standard ruler • reduce fractions to their lowest terms • change improper fractions to proper fractions
