Lesson 2: World War I

In this Grade 5 World History and Geography lesson, students explore the major military campaigns of World War I, learning key concepts such as propaganda, trench warfare, and the strategic differences between the Western Front and the Eastern Front. The lesson examines how the Schlieffen Plan failed, how stalemate developed along the Western Front, and how shifting alliances — including Italy joining the Allied Powers — shaped the war from 1914 to 1915. Students also use a graphic organizer to track how the Allied Powers and Central Powers evolved throughout the conflict.

Section 1

Soldiers Transform Fields into Deadly Trench Systems

Armies dug elaborate trench networks protected by barbed wire and machine guns, creating a deadly stalemate on the Western Front. New technologies like machine guns made traditional offensive attacks tragically ineffective.

Section 2

Governments Expand Powers to Fuel War Efforts

Nations shifted to planned economies where governments controlled prices, rationed supplies, and regulated industries. Military needs required total war mobilization, blurring the line between soldiers and civilians.

Section 3

Women Step Into New Roles During Wartime

As men left for battle, women took previously unavailable jobs as truck drivers, factory workers, and farm laborers. Though many positions proved temporary, these contributions helped advance voting rights in several countries.

Section 4

Nations Use Propaganda to Maintain Morale

Governments spread ideas to influence public opinion, censor newspapers, and arrest protesters. Even democratic countries expanded police powers to maintain public support as the devastating war dragged on.
