This document consists of performance, computational, and communication modules used by the Working Smart workplace literacy project, a project conducted for the hotel and food industry in the Los Angeles area by a public school district and several profit and nonprofit companies. Literacy instruction was merged with job requirements of the customer service job classifications. The performance modules cover: (1) preparing the work area, including cleaning the work area and stocking supplies; (2) serving the customer, including greeting the customer, taking the order, processing the order, and completing the order; and (3) cashiering, including setting up a cash drawer, ringing up sales, and checking out at the end of a shift. A worksheet that accompanies each performance module identifies duties and tasks, tools and equipment to be used, references and resources, criteria for successful completion, a description of the pretest, learner activities, teacher activities, materials needed, and prerequisite instruction. The communication modules cover reading comprehension, writing business correspondence, speaking, completing forms, asking questions, taking notes, and using appropriate nonverbal communication. The computational modules cover reading, writing, adding, subtracting, and multiplying whole numbers; reading, writing, rounding, subtracting, and multiplying decimals; reading and writing percents; computing discounts, markup, tax, commission, and interest; using a calculator; and estimating. The communication and computational modules contain pretests, instruction, practice, posttests, and notes for the instructor. (CML)
