Fraction Operators - A Neglected Concept

Abstract: Fraction operators are found everyone and children are familiar with a variety of models, So it is not the use of fraction operators that is neglected; it is the concept of fraction operator that is neglected. This weakness carries over into percents. A student who is confused about the difference between the number "two-fifths"and the operator "two fifths of" will end up having trouble understanding how to distinquish between the different types of percent problems.

This topic can be presented as a seminar or a workshop. Topics include:

  • Basic Minfro Math theory
  • The difference between a fraction and a fraction operator
  • Practical models and exercises to strengthen student's understanding
  • The relationship between fraction operators and the various types of percent problems.
