Developed by educators from the Emily Griffith Opportunity School, this teacher's guide was developed for a 4-hour workshop to teach employees how to read the charts and graphs they need in the workplace. The unit covers four types of graphs: pictographs, bar graphs, line graphs, and circle graphs. The guide is divided into four sections: reading charts, reading graphs, reasons for using graphs and charts, and a vocabulary exercise. Sections include information and problems to solve, with content drawn from a hospital setting. An answer key is provided. Contains 3 references. (KC)
