Compare and contrast poetry lyrics! Teach students to compare and contrast for state test assessment. Carl Sandburg’s “Grass” and John McCrae’s “In Flanders Fields” are both poems written during World War 1. The battlefields are unique to each poem but the overall theme is universal. Both poems are written with voice and passion.Students will compare and contrast content, language, tone, structure and theme to prepare them for the short answer response questions on end-of-the-semester tests
