Classical Conversations has developed its own timeline of 161 historical events, representing major cultures on every continent. The events are divided into seven ages and produced as cards similar to the Classical Acts & Facts Science Cards, with the event title on the front and a fuller description of the event on the back. Each card front also contains a beautiful memory peg image. Images were chosen to serve families all the way through cultural studies in the upper levels of Challenge. The back of each card also includes a world map pinpointing the event location and a general timeline illustrating when the event occurred relative to known history. The Modern World pack includes the Age of Industry, the Age of Information and Globalization, and the U.S. Presidents.
