# Unit A2: Equations and Inequalities

• Listed below are the NYS Grade 6 Common Core Performance Standards for Unit A2: Equations and Inequalities.

With each Performance Standard are "I Can Statements" students work on throughout the course of the Unit. At the end of the Unit, the students will be assessed on their ability to perform the actions in each "I Can Statement."

Finally, under the
"I Can Statements" are a list of Topics. You will find extra practice resources, videos, class notes, and homework answers by clicking on the appropriate link.

6.EE.5
Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.

"I Understand that Solving an Equation means to find the Value that makes it true and Solving an Inequality means to find the Set of Values that make it true."

6.EE.6

Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

"I Understand that a Variable can Represent an Unknown Number or Set of Numbers."

6.EE.7
Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all non-negative rational numbers.

"I Can Write Equations to Represent Real-World Situations."

"I Can Solve Equations by using Inverse Operations to Isolate the Variable on one side of the Equal Sign."

6.EE.8
Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

"I Can Write an Inequality and Graph the Solution Set on a Number Line to Represent a condition in a Real-World Situation."

"I Can Solve an Inequality for a Variable and Graph the Solution Set on a Number Line."

6.EE.9
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

"I Can Explain the Difference between and identify the Independent and Dependent Variable in a Real-World Situation."

"I Can Write an Expression from a Real-World Situation that relates Independent and Dependent Variables."

"I Can Explain the Relationship between Independent and Dependent Variables using Tables, Graphs, and Equations."

6.NS.8
Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.

"I Can Plot an Ordered Pair of Rational Numbers on the Coordinate Plane."
