## Reflection: Intervention and Extension Function Notation - Section 1: Do-Now

Today's Do Now may be challenging for students since domain and range was formally introduced in just the previous class. To support students, I may place a few completed examples (other than the ones already on their paper) on the board. I will use different color markers to identify important features of the graph that will be used to identify the domain and range. Another support for students is to encourage them to drag their finger along to x and y axis to identify where the function lies on the coordinate plane. The domain and range is the place where the function "exists" on the graph. Similarly, students can use a colored pencil or highlighter to underline the x and y axis when the function is beside or above/below it.
