This handout series, developed with support from the LEGO Foundation, provides suggestions games and play-based activities based on a child’s age. The activities for younger children are designed for adults to engage in with children. Activities for later ages allow the adults to step back, enabling children’s independence to blossom as they transition to playing more often with peers.
There are individual handouts for babies, toddlers, children, and teens.
