The guide, written in Spanish, comprises the fourth grade unit of a career education curriculum for migrant students. Focus of the unit is on the tools and tasks of workers in 11 jobs in the construction, communication, and media occupational clusters: heavy equipment operator, architect, mason, carpenter, plumber, electrician, telephone line worker, announcer, photographer, journalist, and performer. An introduction to each job contains vocabulary words pertaining to the job, as well as instructions for conducting the lessons. Student workbook pages contain language arts and mathematics activities that help students determine cause and effect and develop skills in sequencing, classifying, estimating, vocabulary and word skills (synonyms, antonyms, and prefixes), logic, fact finding, and spelling. A pre- and post-test with student test leaflet, teacher guide, and answer sheet utilizes matching and multiple choice questions to measure the extent to which students understand the tools needed and the work performed in the 11 jobs.
