Data from a larger study were used to identify variables that best predict children's perceived usefulness of mathematics [PUM]. Gender differences in PUM scores were also explored using a sample of 300 grade 7 children and 225 parents from February to May 2011 in Mozambique. Surveys and interviews were used to collect data. Consistent with traditional beliefs it appeared that mathematics is viewed as more useful for boys than for girls. Education of parents, school geolocation, and number of siblings were statistically significant predictors of children's perceived usefulness of mathematics.
