Answer Key/Rubric

  1. Terminating decimals are decimals with a finite number of digits, the decimal ends.
    Acceptable examples might include, but are not limited to:  0.25, -2.4, 3.13468
  1. Repeating decimals are decimals that have a digit or a group of digits that repeat over and over forever, without end.
    Acceptable examples might include, but are not limited to:






  1. Acceptable answers might include, but are not limited to:

    1. Not possible.  This decimal is an irrational number as it is nonterminating and nonrepeating and therefore cannot be written as a fraction.
  1. See table for answers:
 
  1. Acceptable responses might include, but are not limited to:
  • The number of digits repeating determines the number of 9’s in the denominator
  • The digits that repeat become the numerator
  1. Student makes a reasonable prediction.
  2. Answer should be: , so it does not follow the pattern. Student accurately assesses their prediction and justifies why or why not it was correct.
