KidCitizen episodes capitalize on the active and social nature of young children's learning. They use primary sources for rich demonstrations, interactions, and models of literacy in the course of innovative hands-on activities that make academic content meaningful, build on prior experiences, and foster visual literacy and historical inquiry. 

The centerpiece of each episode is a photograph from the Library of Congress that is complemented with other primary sources representative of the app’s topic of focus. Images are selected based on research into the qualities of artifacts that are developmentally appropriate for early childhood and elementary grades.
