The Office of Public Instruction has gathered information that we hope will help you in talking to children about war. The resources we have identified provide timely and pertinent information for parents and teachers alike. The list is by no means exhaustive; more information is available on the Red Cross, FEMA, and U.S. Department of Homeland Security web sites.
