Algebra Applications: Series Description
The Algebra Applications series brings real-world, relevant applications of algebra to todays classroom. This series also integrates technology through the use of the Texas Instruments TI-Nspire graphing calculator. The key features of this series include:
•Guided applications that are interdisciplinary and can be done as an in-class group activity.
•All keystrokes are clearly shown.
•Dynamic footage and animations bring math to life.
•Math concepts are developed clearly, making this series an ideal supplement to an Algebra 1 or Algebra 2 class.
Algebra Applications: Quadratic Functions
In this episode of Algebra Applications, three real-world explorations of linear functions are developed:
- Pyrotechnics. Fireworks displays are elegant examples of quadratic function. In this segment the basics of quadratic functions in standard form are developed visually and students are guided through the planning of a fireworks display.
- Forensics. The distance a car travels even after the brakes are applied can be described through a quadratic function. But there is also the reaction time, the split second before the brakes are applied. The total distance is known as the stopping distance and this segment analyzes the quadratic function. This is an equation that can be used by accident investigators.
- Medicine. From the time a baby is born to the time it reaches 36 months of age, there is dramatic growth in height and weight. An analysis of CDC data reveals a number of quadratic models that doctors can use to monitor and growth and development of children.
