# Conics Introduction and Parabolas

##### This Conics Introduction and Parabolas lesson plan also includes:

Where did conic sections get their name? The equation and graph of a parabola are developed from the definition of the conic section. Teacher examples on graphing the equation and writing an equation from the graph round out the plan.

##### Instructional Ideas

• After developing the equation of a parabola from the definition, compare what is known about quadratic equations and the equation of parabola, both algebraically and graphically
• Extend the lesson to discuss the changes if the vertex was not at the origin; start with vertical or horizontal shifts before combining the two shifts
##### Classroom Considerations

• Only refers to parabolas with a vertex at the origin
• This resource is only available on an unencrypted HTTP website. It should be fine for general use, but don’t use it to share any personally identifiable information
##### Pros

• Provides a visual representation of what constitutes a conic section
