Access Point #: MAFS.912.A-REI.2.AP.3b

Solve linear inequalities in one variable, including coefficients represented by letters.
Clarifications:

Essential Understandings

Concrete:

  • Using manipulatives to represent variables.
  • Identify the unknown quantity when given an inequality and labeled figure.
  • Use manipulatives to solve linear inequalities.
Representation:
  • Understand formula representation (e.g., “h” in the equation means height).
  • Use letters to represent numbers.
  • Solve inequalities and one variable.
    For example:
    2x+4<10
    x<3
  • Recognize symbols for equals (=), addition (+), and multiplication (×), less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥).
General Information
Number: MAFS.912.A-REI.2.AP.3b
Category: Access Points
Date Adopted or Revised: 05/14
Cluster: Solve equations and inequalities in one variable. (Algebra 1 - Major Cluster) (Algebra 2 - Supporting 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.
