Math is all about finding solutions and connections you didn't expect! Young mathematicians often first discover nonlinear patterns when graphing quadratic functions. The lesson begins with the vocabulary of a quadratic graph and uses the idea of symmetry to explain the quadratic pattern.

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
