The BUILD Program (Businesses United to Increase Literacy Development) was conducted from June 1991 through December 1992 as a cooperative workplace literacy program joining Arapahoe Community College and four companies in Littleton, Colorado. This document consists of two modules for the mathematics (computation) classes of the program. The first module, "Workplace Learning Skills," by Jennifer Burkhart, contains four lessons that cover the following: a pretest (from the General Educational Development mathematics book), calculators in the workplace, parts of the whole, and graphs and charts of quality control. Lessons include an objective, required materials, allotted time, outlines of activities with instructor's notes, appendixes containing handouts or transparency masters of practice computations, and individual student activities. The second module, by Mark Sullivan, contains three lessons for instruction in computation in English as a Second Language. Topics are whole numbers, basic mathematical functions, and the national debt. Lesson plans include an objective, required materials, time allotted, and activities.
