High School Algebra 1
The lessons preceding this one focused on the concept of rates of change and slope. The students learned how to write equations of lines and how to switch between graphical (graphs) and algebraic (equations) representations of the same model. This lesson allows the students to apply that knowledge to a real-world situation, using data to create graphs, write equations, assess reasonableness, and make predictions. The differentiated lesson will include an array of different types of data depending on student interest and readiness level. Some students may choose to use Red Cross data for their Excel activities if the advanced organizer interests them, but they are allowed to choose the data that they use. The technology used in this lesson is a good way to help the students visualize the material. It will also introduce them to tools that may prove useful in other aspects of their lives in and out of school. (In a school where these technologies are not available, other visual aids can easily be supplemented.) The visual aids and technology will help engage student interest, as well as help the students to develop some practical skills that may prove necessary in the “digital age.”
