Parents who are uneasy about their own math skills often worry about how best to teach the subject to their kids.

Well ... there's an app for that. Tons of them, in fact. And a study published today in the journal Science suggests that at least one of them works pretty well for elementary school children and math-anxious parents.

A team from the University of Chicago used a demographically diverse group of first-graders and their parents — nearly 600 in all — across a wide swath of Chicago. One group got to use an iPad app called Bedtime Math, built by a nonprofit with the same name. (The app is also available for Android, but we're told most used the iPad version) The no-frills app uses stories and sound effects to present kids with math problems that they can solve with their parents.

**ABSTRACT**

With a randomized field experiment of 587 first-graders, we tested an educational intervention designed to promote interactions between children and parents relating to math. We predicted that increasing math activities at home would increase children’s math achievement at school. We tested this prediction by having children engage in math story time with their parents. The intervention, short numerical story problems delivered through an iPad app, significantly increased children’s math achievement across the school year compared to a reading (control) group, especially for children whose parents are habitually anxious about math. Brief, high-quality parent-child interactions about math at home help break the intergenerational cycle of low math achievement.
