What Is an Equation? 
Your students may know how to solve equations (or not), but do they know the underlying mathematical processes and properties involved in solving them? Do they have sufficient vocabulary to explain their steps in solving an equation? More than memorizing an algorithm, the ability to define and use the properties of equality, as well as other key parts of the equationsolving process are essential for mathematical competence. The ability to analyze and use logical reasoning are skills that go beyond the math classroom. In this module, students learn the basics of the equationsolving process. These principles apply to any equation a student is solving and provide a needed foundational reinforcement for students. 

Solving TwoStep Equations 
In this module students learn how to solve twostep equations. Students are shown how to solve these equations using the Properties of Equality (Addition, Subtraction, Multiplication, and Division). Specifically, students work with the following equation types:
Just as important as solving these equations, students are shown how to recognize such equations. It's in the recognition of the equation type that students can reason their way to the solution, by deciding which of the Properties of Equality to use. 

VIDEO: Algebra Applications: Inequalities 
In this episode of Algebra Applications, two realworld explorations of inequalities are developed. Hybrid Cars. An examination of the equations and inequalities that involve miles per gallon (mpg) for city and highway traffic reveals important information about hybrid cars and those with gasolinepowered engines. Floods in Venice. Venice experiences a great deal of flooding, and with the expected rise of sea levels over the next century, this ancient city is in peril. Through a series of inequalities, students analyze the impact of flooding.

VIDEO: Algebra Applications: Inequalities, Segment 1: Hybrid Cars. 
With the increasing demand worldwide for cars, the cost of gasoline continues to rise. The need for fuelefficient cars makes hybrids a current favorite. An examination of the equations and inequalities that involve miles per gallon (mpg) for city and highway traffic reveals important information about hybrid cars and those with gasolinepowered engines. Students use the Graphs and Geometry features of the TINspire.

VIDEO: Algebra Applications: Inequalities, Segment 2: Floods in Venice. 
The city of Venice is slowly sinking into the Adriatic Sea. So what does a city whose streets are full of water do about flooding? Venice experiences a great deal of flooding, and with the expected rise of sea levels over the next century, this ancient city is in peril. Through a series of inequalities, students analyze the impact of flooding, rising sea levels, and sinking have on this grand, ancient city. Students use the Lists and Spreadsheets and the Program Editor features of the TINspire.

VIDEO: Algebra Nspirations: Inequalities 
Used in just about any industry, inequalities, like equations, are fundamental building blocks of algebra. Written and hosted by internationally acclaimed mathematics educator Dr. Monica Neagoy, this video explores inequalities—concepts, properties, solutions, and notations— connects them to realworld contexts, and uses the TINspire to make the algebra meaningful. The focus of this program is on linear inequalities in one and two variables. Concepts explored: Equations, inequalities.
