Math Curriculum Comparison Study

This study compared four elementary math curricula—Investigations in Number, Data, and Space; Math Expressions; Saxon Math; and Scott Foresman-Addison Wesley Mathematics (SFAW)/enVision Math—for students in 1st and 2nd grades. Schools were randomly assigned to use one of the four curricula. Each curriculum was implemented as the core math program in participating schools, with teachers receiving training from publishers before the school year began. The curricula differ in their approaches to mathematical emphasis, instructional approach, and supports for teachers. Implementation involved daily math instruction delivered by classroom teachers using the assigned curriculum materials, including textbooks, workbooks, manipulatives, and other resources specific to each program.
