Reflection: Developing a Conceptual Understanding Graphing Linear Functions Using Given Information - Section 2: Guided Notes + Practice

 

This lesson builds nicely to allow students to move successfully to independent practice. The independent practice is especially successful due to the structures built into it. For example, the self-check element allows students to test their knowledge without needing teacher input and is supported by a culture of accountability in the class. Additionally, the Do Now is an important building block that allows students to make the jump to calculating slope in example three.

As mathematicians, it is important that student understand the difference between parameters and variables. By this point students already know that parameters do not change but the variables such as x and y do change. However, this lesson provides an excellent opportunity to solidify that understanding. Although m and b are variables, they are also parameters and therefore do not change for any given equation.
