In the U.S. the fifth-grade mathematics curriculum is largely devoted to building fraction skills, providing an essential foundation for future success in mathematics (National Mathematics Advisory Panel, 2008). Unfortunately, students in the U.S. struggle with fraction proficiency (National Assessment of Educational Progress, 2022; Organisation for Economic Co-operation and Development, 2018). Even when teachers facilitate interventions for struggling students those interventions may not be aligned with student need (Riccomini, 2005). Additionally, teachers struggle to identify research-based practices (RBPs) when presented with student data (Means et al., 2009). The purpose of this study was to create and test a flowchart that could be used by teachers to help them determine appropriate RBPs for fifth grade fraction skill remediation. Two experts in the field of math remediation served on a panel to create a gold standard for the flowchart, and 42 teachers certified to teach fifth-grade math participated in an experimental study to test the flowchart. Use of the Fraction Error Flowchart resulted in a statistically significant improvement (p
