A.1 
The student will represent verbal quantitative situations algebraically and evaluate these expressions for given replacement values of the variables. 

Essential Knowledge and Skills 
 Evaluate algebraic expressions for a given replacement set to include rational numbers.
 Evaluate expressions that contain absolute value, square roots, and cube roots.

Essential Understandings 
 The numerical value of an expression is dependent upon the values of the replacement set for the variables.
 There are a variety of ways to compute the value of a numerical expression and evaluate an algebraic expression.
 The operations and the magnitude of the numbers in an expression impact the choice of an appropriate computational technique.
 An appropriate computational technique could be mental mathematics, calculator, or paper and pencil.
