We examined how parent math attitudes and practices relate to emergent math skills in 72 preschoolers from low-income households. Specifically, we investigated parents' views about the importance of math learning, their confidence in teaching math, their perceptions of child interest in math, and their time spent engaging their child in math activities. For comparison, we also investigated these attitudes and practices surrounding preliteracy development. Parents rated math as significantly less important than reading and perceived their children as being significantly less interested in math than reading. Reports of confidence in teaching math and perceptions of child interest in math were positively related to time spent engaging preschoolers in math activities. In turn, global reports of time spent engaging preschoolers in math activities were positively related to preschoolers' actual math achievement. These findings strengthen the case that parental beliefs surrounding math predict practices associated with early math development.
