This lesson is a great way to incorporate technology in the middle school math classroom. Students use the interactive and convenient online graphing calculator website Desmos.com to develop a deeper conceptual understanding of linear functions. Students will specifically draw connections between the relationships of the slope and y-intercept of a linear function and the effect it has on the shape of the function.
This is a very student-centered activity. Students may work together in pairs or individually. The lesson is created in a way where questioning guides student work, scaffolds student thinking, encourages students to make conjectures, and eventually draws students to make the mathematical connections intended for the lesson.
This activity requires access to internet for every student.
This activity is intended for students who have basic or no prior knowledge of linear equations and how slope and y-intercept affect the behavior of a linear function.
This product also includes a section that can be used either for a lesson wrap up in class or homework. This section also requires access to the internet. Students write down their final generalizations from the lesson and test out their theories using the slider function in Desmos.
