The student will
a)  write verbal expressions as algebraic expressions and sentences as equations and vice versa; and
b)  evaluate algebraic expressions for given replacement values of the variables. 
Essential Knowledge and Skills 
  • Write verbal expressions as algebraic expressions. Expressions will be limited to no more than 2 operations.
  • Write verbal sentences as algebraic equations. Equations will contain no more than 1 variable term.
  • Translate algebraic expressions and equations to verbal expressions and sentences. Expressions will be limited to no more than 2 operations.
  • Identify examples of expressions and equations.
  • Apply the order of operations to evaluate expressions for given replacement values of the variables. Limit the number of replacements to no more than 3 per expression.
Essential Understandings
  • How can algebraic expressions and equations be written? Word phrases and sentences can be used to represent algebraic expressions and equations.
