## Reflection: Intervention and Extension Different Forms and Different Parameters - Section 2: Use this Desmos Graph to Check Your Work

It's not essential to this lesson, but I might ask students to sketch graphs of these functions.  There are two reasons to possibly go this route:

• As an extension.  For students who have breeze through the work, sketching a few graphs in their notes will set them up for what's next.
• As an intervention, sketching graphs can be a great way to focus struggling students on what we're doing here.  There's a lot going on in this assignment: multiple sliders and sixteen different quadratic functions, each in three different forms.  Modeling a sketch of a the first function before telling students to sketch just a few more can help to give the work some focus.
