Instructional Ideas
- Examine the pattern of symmetry closely with an "a" value of one; as you move away from the vertex, the vertical pattern will be 1, 4, 9, etc.
- Connect the location of the vertex to the transformations of the parent function
Classroom Considerations
- Projection capabilities are helpful to show photos of quadratic shapes in the world
- The ninth lesson in a 26-part series
Pros
- A conceptual approach to graphing quadratic functions that discourages memorization
- Handouts, keys, and a detailed teacher guide are included
- Opener and exit ticket are provided
Cons
- None
