      Learning outcome

      I can explain what World War I was.

      1. WWI was a war that took place between 1914 to 1918 and involved countries from across the globe.
      2. It was the biggest war that had ever been fought at the time which is why it was called the Great War.

      Common misconception

      Children may think that the word 'Great' when referring to WWI may mean that the war was a great idea.

      To remind pupils that 'Great' in this context refers to the both the size and scale of the war.
