Nearly one-third of children entering kindergarten are considered overweight or obese. To help teachers and parents teach healthy habits to children before age 5, University of Nevada Cooperative Extension launched the Healthy Kids Resource Center website. The website offers evidence-based research, resources, curricula, activities and materials that focus on obesity prevention. Key features of the site are “toolboxes,” resource collections related to a specific area of health. The first toolbox is the Physical Activity Toolbox. The website is www.unce.unr.edu/healthykids
