The evidence is in:

  • Kindergarten 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).
