EA-2
Through the process standards the student will demonstrate an understanding of the real number system and operations involving exponents, matrices, and algebraic expressions.
EA-2.1 / Exemplify elements of the real number system, including integers, rational numbers, and irrational numbers. / Under CC, students must understand integers, rational, and irrational numbers over the course of the 3 years in middle school.
EA-2.2 / Apply the laws of exponents and roots to solve problems. / CC has moved this to grade 8.
8.EE.1 and 8.EE.2
EA-2.3 / Carry out a procedure to perform operations (including multiplication and division) with numbers written in scientific notation. / CC has moved this to grade 8.
8.EE.3 and 8.EE.4
EA-2.4 / Use dimensional analysis to convert units of measure within a system. / N.Q.1 - Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. / Dimensional analysis is also addressed in grades 7 and 8. (8-5.6) The intent of the CC standard here is broader than the intent of the SC standard. Although there is a minimal match, dimensional analysis will move to grade 6 under CC.
EA-2.5 / Carry out a procedure using the properties of real numbers (including commutative, associative, and distributive) to simplify expressions. / A.REI.1 - Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method. / Not a direct match, but using properties of operations to simplify would be used. However the properties of equality would also be used. See page 90 in CC standards.
EA-2.6 / Carry out a procedure to evaluate an expression by substituting a value for the variable. / CC has moved this to grade 6.
6.EE.1 and 6.EE.2c
EA-2.7 / Carry out a procedure (including addition, subtraction, multiplication, and division by a monomial) to simplify polynomial expressions. / A.APR.1 - Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials. / The focus of this CC standard is closure on the set of polynomials under the operations of addition, subtraction, and multiplication. However the student’s ability to perform these operations is implied in this standard.
Operations with polynomials is also addressed in SC Algebra 2 standards.
EA-2.8 / Carry out a procedure to factor binomials, trinomials, and polynomials using various techniques including expressions with a greatest common factor, difference between two squares, and quadratic trinomials. / A.SSE.2 - Use the structure of an expression to identify ways to rewrite it. For example, see x4 – y4as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2). / This CC standard is much broader than the match to this one standard. The CC intent is to use structure to identify ways to rewrite a variety of expressions to put them in amore useful form for a specific purpose.

EA-3.1 / Classify a relationship as being either a function or not a function from data presented through a table, set of ordered pairs, or graph. / 8.F.1 - Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
F.IF.1 - Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x). / CC will initially address this concept in grade 8.
EA-3.2 / Use function notation to represent functional relationships. / F.IF.1 - Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
F.IF.2 - Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context. / The CC standard extends the SC standard to interpreting the notation in the context of a problem situation.
EA-3.3 / Carry out a procedure to evaluate a function for a given element in the domain. / F.IF.2 - Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context. / The CC standard extends the SC standard to using and interpreting the notation in the context of a problem situation.
EA-3.4 / Analyze the graph of a continuous function to determine the domain and range of the function. / F.IF.1 - Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
F.IF.5 – Relate the domain of a function to its graphand, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of persona-hours it takes to assemble n engines in a factory, then the positive integers would be appropriate domain for the function. / This SC standard emphasizes identifying the domain and range based on an analysis of the graph. The CC extension includes determining the domain by analyzing quantities appropriate to the problem context. SC standards address this part of the standard in EA-5.10.
EA-3.5 / Carry out a procedure to graph parent functions
(including y = x, y = x2, y = , y = , and y = / F.IF.7b - Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.★

EA-3.7 / Carry out a procedure to solve literal equations for a specified variable. / A.CED.4 - Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm’s law V =IR to highlight resistance R.

Compare an algebraicsolution to an arithmetic solution, identifying the sequence of theoperations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
b. Solve word problems leading to inequalities of the form px + q r or px + q r, where p, q, and r are specific rational numbers. Graphthe solution set of the inequality and interpret it in the context ofthe problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale.

a. Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
b. Solve systems of two linear equations in two variables algebraically and estimate solutions by graphing the equations.Solve simple cases by inspection.For example, 3x + 2y = 5 and 3x +2y = 6 have no solution because 3x + 2y cannot simultaneously be 5and 6.
c. Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for twopairs of points, determine whether the line through the first pair ofpoints intersects the line through the second pair. / For A.REI.11, CC requires students in Algebra 1 to focus on linear and exponential and to learn the general principle of solving f(x) = g(x).
