Using whole number numerators from 8 to 20 and odd whole number denominators from 3 to 7, identify rational decimal expansions.
Clarifications:

Essential Understandings

Concrete:

  • Use base ten manipulatives to divide numbers.
  • Understand that the use of 3.14 for π is a rounded, approximated number (e.g., use 22/7 in a calculator to approximate π).
  • Match characteristics of irrational and rational numbers.
Representation:
  • Use a calculator to divide numbers from 8 to 20 and odd whole number divisors from 3 to 7.
  • Identify the characteristics of an irrational number.
  • Identify irrational decimal quotients.
General Information
Number: MAFS.8.NS.1.AP.1b
Category: Access Points
Date Adopted or Revised: 06/14
Cluster: Know that there are numbers that are not rational, and approximate them by rational numbers. (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.
