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.

- General mathematics achievement: Positive impact (

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.
