The animated PowerPoint key is a new edition to this lesson. It enables the whole class to check their answer as they go. It is colorful, and some parts of the key explain how to do the problem. This really saves me time as a teacher. Furthermore, students love it when I project the answers onto a smart board or promethean board so they can check their answers as they go. It helps them learn better and see their errors more quickly. It also leads to good class discussions.
This product explores the relationship between tables, graphs, repeated addition, and equations for linear relationships. There are three real-world scenarios in this lesson. The first real world scenario, “I’m Rich”, explores how the slope intercept form of an equation can help students to calculate savings over time. The second scenario , “I’m Cruising”, involves a basic scenario in which one is travelling from Denver, Colorado, at an average speed of 70 mi/h and he or she needs to calculate the distance from Lincoln, Nebraska, at various times. The third scenario, “It sure is cold outside”, looks at the relationship between temperature and wind chill. These scenarios really help students get a better conceptual understanding of y = mx + b.
