Elementary School Math. What Works Clearinghouse Topic Report

What Works Clearinghouse

The What Works Clearinghouse (WWC) looked at elementary school math curricula designed to promote math knowledge and skills among elementary school students (average ages 5 to 10 years). Curricula included in this review are replicable, materials-based instructional programs that cover one or more of the following content areas: numbers, arithmetic, geometry, pre-algebra, measurement, graphing, and logical reasoning. This review considered only core, comprehensive math curricula and focused on student achievement in mathematics as the key outcome. The findings in this topic report summarize the first wave of WWC elementary school math intervention reports produced in 2006-07. WWC looked at 340 studies. Of these, 237 were assessments of interventions that qualified for review; the other 103 could not be categorized by intervention. Of the 237 studies, 9 studies of 5 curricula met WWC evidence standards, 2 without reservations and 7 with reservations. Altogether, the WWC looked at 73 interventions: 5 had studies that met WWC standards with or without reservations, 67 had studies that did not meet WWC evidence screens, and 1 had a single-case study, which is still under review. In looking at the one outcome domain for the five elementary school math curricula, "Everyday Mathematics" had potentially positive effects on math achievement. Four other curricula had no discernible effects on math achievement. Includes appendix. (Contains 2 tables, 1 figure, and 6 footnotes.)
