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 
 Translate verbal quantitative situations into algebraic expressions and vice versa.
 Model realworld situations with algebraic expressions in a variety of representations (concrete, pictorial, symbolic, verbal).

Essential Understandings 
 Algebra is a tool for reasoning about quantitative situations so that relationships become apparent.
 Algebra is a tool for describing and representing patterns and relationships.
 Mathematical modeling involves creating algebraic representations of quantitative realworld situations.
