The Colombian Exchange. Mrs. Letizia and her students visited the Makerspace where students demonstrated their knowledge of this topic. Students were placed in groups and took turns choosing a card showing a product. They had to use their previous knowledge and inferencing skills to determine if the product originated from the Old World or New World. When looking at a product, they inferred its origin by thinking about if it was in the world at the time of Jesus. Then, students worked with their group members and each took turns programming the Dash robot to travel to the correct path. The students had fun while using engineering, sequencing and critical thinking skills!
