This action research was driven by the researcher's interest in reading fluency and specifically about using a class-wide intervention to help increase students' words per minute using Varied Practice Reading. The researcher is a third-grade teacher in her 7th year of teaching, where her own students participated in the class-wide intervention. The five week intervention was conducted on the students' fluency to analyze the effectiveness of the class-wide Varied Practice Reading intervention. Throughout the five weeks, oral reading fluency was progress monitored for six students that were identified as persistently at-risk or at-risk based on Fastbridge 3rd grade fall benchmark score. Findings revealed common pieces of effective reading fluency specially with an increase of correct words per minute when reading orally aloud. The research was conducted to result in future instruction in whole building classrooms to solidify the decisions made in regard to fluency interventions.
