In the Mentor Monday from 1/23/23 Todd Nussen discusses strategies used for economics and labor. These activities and lessons are critical for teaching students about the basic economic and globalization principals our world revolves around. I'm positive I'm not the only one who has come up with some twists to the Assembly Line activity posted in WHP. This lesson plan for 4.1 is solid to be sure, but some mods are always fun if the teacher wants to tackle a new approach. I've taught students about assembly lines for years using Lego building blocks. The materials I'm linking in will give enough details I'm sure you can figure it out without me making a long post.
Assembly Line Presentation and Video
In times where I don't have the wherewithal to make the Legos work, I've used this origami box plan for the "factory" experience too. Sometimes this can be used for the assembly line, or can be used in a "factory setting" with managers and line bosses, and workers. I've also been the "boss" and I (gently but firmly) pressure teams of students to produce MORE AND MORE with loud factory noise from YouTube in the background!
