Analyzing secret messages from the past can also be a fun way for students to gain perspective into historical events while simultaneously practicing real-world mathematical and computational thinking skills.
During an event as large and disruptive as World War I, individuals, organizations, and governments had to make difficult choices between competing societal needs. Examining sports pages from WWI-era newspapers provides an intriguing look at the interplay between celebrity, public entertainment, and wartime needs.
Analyzing primary sources using mathematical reasoning can help students quantify historical changes over time, giving them a concrete sense of scope and scale, while providing meaningful historical perspective.
