Based on the pretest sample, prior math research, and our previous findings, we anticipated students would make the most mistakes in Combining (C: Student combines numerators together and denominators together), Add All (AA: Student adds together all the numbers of the fractions and finds a total sum), Select Denominator (SD: Student uses one of the denominators in the answer without finding the equivalent fraction), and Equivalent Fractions (EQ: Student makes an error when attempting to find an equivalent fraction).
A similar error was AA where students added all numerators and denominators to find a total sum, but because this was far less common we chose to target the more populated C error in our analysis.
