After Two Years, Three Elementary Math Curricula Outperform a Fourth

This evaluation brief aims to help educators understand the implications of math curriculum choice in the early elementary grades by presenting new findings from a study that examined how four math curricula affect students' achievement across two years—from 1st through 2nd grades. The four curricula were Investigations in Number, Data, and Space (Investigations); Math Expressions; Saxon Math (Saxon); and Scott Foresman-Addison Wesley Mathematics (SFAW), which the developer revised and renamed enVision Math (enVision) during the study. These curricula are widely used and differ in their approaches to teaching and learning.

Our findings also suggest that switching between some of the study's curricula does not harm student achievement and can even be beneficial.
