Basic Linear Functions are a big topic in Pre-Algebra and Algebra 1. If you are looking for a PowerPoint to lead your students through the procedures to enter a table, graph the data, and write the expression (or equation) using the CASIO graphing calculator, HERE IT IS! The examples start leading the students with 'baby' steps, but as the PowerPoint progresses the students are offered the chance to progress more independently. The examples are real-world and engaging. Once the students master the list, graphs, and linear expressions using the CASIO, the world of math using this technology is massive!
I've been teaching mathematics, international studies, and media design since 1998 in an urban district located in the southeast region of the USA. Before becoming a teacher, I worked as an electrical engineer for several years.
