PBL Pathways
Arch Project
Model real-life structures with mathematics. A project-based lesson presents a problem situation requiring classes to develop a function to model the St. Louis Arch and the Rainbow Bridge in Arizona. They create their models by...

Ministerio De Educacion Y Ciencia: La Function Cuadratica. Parabolas.
This is an interactive activity to explore the second-degree polynomial function. It goes from the simplest case, y=x^2 to different translations.
Texas Instruments
Texas Instruments: St. Louis Curves or Arch? You Pick!
Students explore curve fitting and translations of the parabola.
Texas Instruments
Texas Instruments: Exploring Quadratic Data With Transformation Graphing
Students practice with the parameters of the vertex form of the parabola and their effect on the shape of the curve. They use this concept to find a quadratic model. They also use translation and dilation to change the general parabola.
