In anticipation of the career fair tomorrow, students spent the first half of class comparing the US economy to what they have learned about ecosystems. After five minutes of private think/write time, students worked in row groups (with the students seated in their row) to share their ideas and then represent them on their row’s white board. Students were pressed to consider how education fits within the larger economic system. We discussed the idea that education can be compared with the sun, as it adds energy (ideas and qualified workers) into the system. For the second half of class, students worked with their row groups to fill out a summary table for the current unit. Each row worked on one of four sections of the summary table, after which students compared their work the completed answer key. The summary table will be a useful study tool for the unit exam scheduled for next Wednesday.
