Preschoolers’ math skills are powerful predictors of future academic success. Home is the key learning environment, but barriers such as time and parental math anxiety can limit positive math interactions within families. Together Math maximizes social meaningfulness by placing a child’s own parent within a preschool math game. The voice of a parent replaces the standard in-app audio, improving learning and promoting spontaneous transfer of math talk to the real world. Together Math interrupts the link between parental math anxiety and student math achievement, preparing young learners to thrive at school.
