VIDEO: Algebra Applications: Variables and Equations 
In this episode of Algebra Applications, two realworld explorations are developed: Biology. Analyzing statistics from honey bee production allows for a mathematical analysis of the socalled Colony Collapse Disorder. Geology. Why do rivers meander instead of traveling in a straight line? In this segment the geological forces that account for a river’s motion are explained.

VIDEO: Algebra Applications: Variables and Equations, Segment 2: Honey Production. 
Honey bees not only produce a tasty treat, they also help pollinate flowering plants that provide much of the food throughout the world. So, when in 2006 bee colonies started dying out, scientists recognized a serious problem. Analyzing statistics from honey bee production allows for a mathematical analysis of the socalled Colony Collapse Disorder.

VIDEO: Algebra Applications: Variables and Equations, Segment 3: River Ratios. 
Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? Furthermore, what information can the ratio of the river’s length to its straightline distance tell us? In this segment the geological forces that account for a river’s motion are explained. In the process, the socalled Meander Ratio is explored. Students construct a mathematical model of a meandering river using the TINspire. Having built the model, students then use it to generate data to find the average of many Meander Ratios. The results show that on average the Meander Ratio is equal to pi.

VIDEO: Algebra Nspirations: Variables and Equations 
Ever since the mathematics of the Babylonians, equations have played a central role in the development of algebra. Written and hosted by internationally acclaimed mathematics educator Dr. Monica Neagoy, this video traces the history and evolution of equations. It explores the two principal equations encountered in an introductory algebra course – linear and quadratic – in an engaging way. The foundations of algebra are explored and fundamental questions about the nature of algebra are answered. In addition, problems involving linear and quadratic equations are solved using the TINspire graphing calculator. Algebra teachers looking to integrate handheld technology and visual media into their instruction will benefit greatly from this series. Concepts explored: Variables, equations, functions, formulas, linear functions and equations, quadratic functions and equations, solving equations graphically.
