Reflection: Students with Disabilities Vertex Form to Standard Form - Section 3: Discussion & Closing


It is usually a few lessons after this one that I realize students are confused about going from vertex to standard form. At the end of this lesson they usually seem to have a firm grasp of what to do.  But once I introduce going from standard form to vertex form, they seem to be confused when we spiral back to this content.  This year, I've tried a few different things to help struggling students master vertex to standard form.

First, I think it helps some students to generate a list of steps.  Although it may seem superfluous initially, when they start to work in the opposite direction their written steps may help them be clear about what they're doing.

Second, I try to revisit this content in warm up activities, especially when we're learning to complete the square.  I want students to remember that going from vertex to standard form is its own, separate task.

Lastly, I try to remind students that they are really just simplifying an equation here by following the order of operations. I often see students try to adjust the constant term when going from vertex to standard form, an idea they have picked up from going the other direction.  I try to encourage them to just follow the algebra here, rather than thinking about it too much! There's plenty of thinking to do when they go from standard to vertex form.

Vertex Form to Standard Form

Unit 4: Quadratics!
Lesson 7 of 18

Objective: SWBAT use an area model to square binomials. Students will be able to rewrite quadratic functions from vertex form into standard form.

Big Idea: Students apply the multiplication models they have recently learned to the task of rewriting quadratic functions from vertex form into standard form.
