Abstract
In this study, 21 participants (control and treatment) were examined based on differences between their abilities to use a variety of strategies to compare fractions after considering the fractions' approximate positions on a number line. A pre-post test and interviews were conducted in Fall 2015 and Spring 2016. Results showed greater gains for the treatment group than the control group in their ability to correctly estimate a fractions' position on the number line and to count fractional intervals on the number line. Even after students in the treatment group developed the ability to correctly place fractions on a number line, these students did not see the number line as a tool to use for comparing fractions, and preferred to use other strategies instead, even faulty strategies.
