Solve an inequality using substitution (e.g., given a budget, a student will select a number [specified set] to remain within budget).

Clarifications:

Essential Understandings

Concrete:

  • Evaluate an expression using substitution (e.g., find the value of x + 4 when x = 2 using manipulatives).
  • Use objects to solve inequalities with whole numbers.

    Evaluate an expression using substitution chart data for the expression 3x with input values of 0, 1, 2, and 3 and output values of 0, 3, 6, and 9 respectively.
Representation:
  • Understand the following symbols: +, -, ÷, =, ×, <, >, ≠, ≤, ≥.
  • Use pictures/tables to solve inequalities with whole numbers (i.e., input/output chart or graphic organizer).
  • Understand the following concept and vocabulary of inequality.

Date Adopted or Revised: 07/14 Cluster: Reason about and solve one-variable equations and inequalities. (Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
