Standards I Can… Standards for Mathematical Practice MCC8.EE.7 Solve linear equations in one variable. a. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = b, or a = a results (where a and b are different numbers). b. Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive Standards for Mathematical Practice Make sense of problems and persevere in solving them. Reason abstractly and quantitatively. Construct viable arguments and critique the reasoning of others. Model with mathematics. Use appropriate tools strategically. Attend to precision. Look for and make use of structure. Look for and express regularity in repeated reasoning. I Can… I can use strategies to create and solve linear equations with one solution, infinitely many solutions, or no solutions.

Vocabulary Word Definition Linear Equation An equation that can be written in the form ax + b = c where a, b, and c are real numbers and a≠0 Integer A whole number; a number that is not a fraction (can be negative). Inverse Operations Pairs of operations that undo each other, for example, addition and subtraction and inverse operations and multiplication and division are inverse operations. Additive Inverse Two numbers whose sum is 0 are additive inverses of one another. Example: ¾ and – ¾ are additive inverses of one another because ¾ + (- ¾) = 0 Algebraic Expression A mathematical phrase involving at least one variable. Expressions can contain numbers and operation symbols.

Continued Vocabulary Word Definition Variable A letter or symbol used to represent a number. Coefficient A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4x) Evaluate To perform operations to obtain a single number or value Solution The value or values of a variable that make an equation a true statement. Like Terms In algebra, like terms are terms that have the same variables and powers. Only the coefficients of like terms can be different.
