Books, Balls, and Blocks is a family engagement strategy developed by Help Me Grow Utah to utilize a community setting to promote developmentally appropriate play, positive parenting, and developmental screening among families, while raising awareness of Help Me Grow. This manual was developed by Help Me Grow Utah, in partnership with the National Center, to outline the critical components of the Books, Balls, and Blocks model and guide Help Me Grow affiliates in adopting this model to enhance their Family & Community Outreach efforts.
