This 4 Corner Cooperative Learning Strategy incorporates Bloom's Taxonomy questions about the NATO & Warsaw Pact political divisions at the end of WWII. Assign the 4 questions provided to a corner (or area) in your room. Present the topic and the 4 related questions to the whole group and give your students some think time. Students will then choose a corner in which they can discuss their chosen topic. Representatives from each corner can share what their respective groups discussed.
