The study described in this report tested an intervention involving a family engagement model designed to promote mathematics learning in preschool children. The intervention model includes a school-based curriculum whereby families attend weekly parent support meetings for nine weeks and use PBS KIDS transmedia suites of digital games, videos, and hands-on activities, all related to early mathematics. Each transmedia suite in the intervention uses an engaging narrative throughout all components. The suites feature many preschool children's favorite media characters such as Curious George, Peg+Cat, and The Cat in the Hat. The intervention model was developed over the past three years, and earlier versions were tested in two previous studies (McCarthy, Li, & Tiu, 2012; McCarthy, Li, Atienza, Sexton, & Tiu, 2013). The latest study builds on these past two studies by developing a scalable model that can be implemented in different preschool locations and by assessing the feasibility of having local preschool staff facilitate its weekly parent meetings.
