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 Building Blocks for Math (SRA Real Math)’s impact on students. Here’s the short version:

Building Blocks for Math (SRA Real Math) is a supplemental mathematics curriculum designed to develop preschool children’s early mathematical knowledge through various individual and small- and large-group activities. It uses Building Blocks for Math PreK software, manipulatives, and print material.

The evidence for Building Blocks for Math (SRA Real Math) covers students in pre-kindergarten.

The outcomes examined include: general mathematics achievement. Here’s what the evidence suggests about Building Blocks for Math (SRA Real Math)’s impact on each outcome:

  • General mathematics achievement: Positive impact ( an average student would be expected to improve by 36 percentile points)

The studies looking into Building Blocks for Math (SRA Real Math) had student samples that were in New York, had students who were White, Black, and Hispanic, were male and female, and received free & reduced price lunch.
