Do not always be maxed out by the vertex. A short video introduces the graphical display of the vertex and zeros of a quadratic function. The presenter provides the definitions of the minimum and maximum of the graph along with explaining where to find them. Next, the presentation continues to show how to find and write the zeros of the graph before finishing up with examples for review.

Instructional Ideas

• Have the class create a flipbook with the vocabulary, definitions, and examples
• For the review examples, have pupils identify the features of the graph that were not included in the example

Classroom Considerations

• The definitions and information provided is all based upon graphs of quadratics

• This video is hosted on YouTube

Pros

• The presentation connects the minimum and maximum to a context the class understands
• The video uses several graphics to reinforce the concept

Cons

• Does not contain the algebraic manipulation that is required of HSF-IF.C.8.a; it might fit better with HSF-IF.C.7.a
