Experimentally proven to increase learning and close achievement gaps!

In a randomized controlled trial, children that played Math Shelf learned six months more than children that played the five most downloaded and best reviewed math apps in 2014. Read the study published in Early Education and Development.



In a quasi-experimental study, children that played Math Shelf learned one year more than students that received classroom mathematics instruction. Read the study published in Computers in Human Behavior.



In a large-scale randomized trial, 500 children that played Math Shelf learned nine months more than children that were taught a research-based hands on mathematics curriculum. Read the article published in the Mathematics Education Research Journal.

The evidence is in:

  • Preschool mathematics knowledge is the best predictor of high school academic success (Watts et al., 2014).
  • Preschool mathematics knowledge predicts adults' earnings potential (Geary et al., 2013).
  • Preschool mathematics knowledge is a better predictor of elementary school academic success than literacy readiness skills (Duncan et al., 2007).
