Staging the Compelling Question
In staging the compelling question “Why do countries need each other?” teachers might begin by showing the YouTube video “Global Ship Traffic Seen from Space” ( and asking students what they think they are seeing. Students may have several hunches, but one or more will likely guess that the video represents shipping routes. Following up on that suggestion, teachers should ask what students think might be on those ships. From the hunches offered, teachers can follow up by introducing and unpacking the word “trade” and what it means to trade goods.
