Welcome to Parsimony’s blog, where we help K-12 educators identify evidence based ways to maximize student outcomes.

This blog post is part of our What Works Clearinghouse review series. The What Works Clearinghouse (WWC) is an initiative by the Institute of Education Sciences (IES) which is the independent statistics, research, and evaluation arm of the United States Department of Education. WWC estimates the effectiveness of programs by evaluating the quality and quantity of evidence for that program.

This week’s blog post is about the evidence behind Everyday Mathematics® ’s impact on students. Here’s the short version:

Everyday Mathematics® is a core curriculum for students in prekindergarten through grade 6. At each grade level, the Everyday Mathematics® curriculum provides students with multiple opportunities to learn concepts and practice skills. Across grade levels, concepts are reviewed and extended in varying instructional contexts.

The evidence for Everyday Mathematics® covers students in 3rd grade through 5th grade.

The outcomes examined include: general mathematics achievement. Here’s what the evidence suggests about Everyday Mathematics® ’s impact on each outcome:

  • General mathematics achievement: Positive impact (an average student would be expected to improve by 11 percentile points)

The studies looking into Everyday Mathematics® had student samples that were in urban areas in Texas.
