Solve simple rational and radical equations in one variable.

Clarifications:

Essential Understandings

Concrete:

  • Identify the variables in an equation.
  • Substitute numbers for variables.
Representation:
  • Understand the following related vocabulary: variable, rational numbers, radical.
  • Solve radical equations. For example, 

    begin mathsize 12px style y space equals space 3 square root of 100 space plus space square root of 100 end style
    begin mathsize 12px style y space equals space 3 left parenthesis 10 right parenthesis space plus space 10 end style
    y = 40

  • Solve simple rational equations in one variable.

Number: MAFS.912.A-REI.1.AP.2a Category: Access Points
Date Adopted or Revised: 07/14 Cluster: Understand solving equations as a process of reasoning and explain the reasoning. (Algebra 1 - Major Cluster) (Algebra 2 - 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.
