Examining the Longitudinal Impact of Zaner-Bloser Building Fact Fluency on School-Level Third-Grade Proficiency, Spring 2021-Spring 2023

Math fact fluency--the ability to quickly and accurately recall basic addition, subtraction, multiplication, and division facts--is a foundational mathematical skill. "Zaner-Bloser Building Fact Fluency (BFF)" was designed to build students' conceptual understanding of arithmetic operations and increase procedural fluency among elementary school students, with the goal of strengthening math learning. LXD Research conducted a study to examine Grade 3 students' math proficiency levels on the standardized Iowa Statewide Assessment of Student Progress (ISASP) across five "Building Fact Fluency" participating schools and 20 similar Iowa comparison schools from spring 2021-spring 2023. One "Building Fact Fluency" pilot school began the program in fall 2021, and four additional schools began the program in fall of 2022. The pilot "Building Fact Fluency" school, Year 2-only "Building Fact Fluency" schools, and comparison schools had a similar percentage of students on grade level at baseline. However, Grade 3 students in "Building Fact Fluency" schools showed consistently greater improvements in the percentage of Grade 3 students on grade level in math.
