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 real-world 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 real-world situations.
