This formative evaluation gathered feedback from parents and their fourth grade children in response to two activities included in the Cyberchase at Home outreach materials. The user-based feedback assisted with the design of new outreach materials. The general goals for the research were to explore reactions to the activity card format; assess appeal and difficulties in implementation of two activities; estimate comprehension of activity content; and evaluate parental interest in further activities and workshops. Cyberchase is the Emmy Award-winning mathematics series and website on PBS KIDS
