I saw this activity on Facebook last year. I don’t know who the teacher is, but the project is posted on North Central Parke Community School Corporation Facebook page.
I created the instructional slide below to facilitate the process with my students. Students had to select an object in the classroom to enlarge or reduce. They needed at least 5 measurements (many students took a lot more than that) and they had to select a scale factor. I provided some supplies but they were welcome to bring others from home. The project had to be completed in the classroom and they had to collaborate with at least one other person.
My students were so engaged, they worked very hard, and they were so proud of their results. Not to mention, they had some a-ha moments during construction. One student in particular made the connection that angles are the same in scaled objects even though the sides change. Now we had investigated and discussed this learning target, but it became evident to her when she was working on her object. YAY!
The first photo gallery includes process photos. I documented our progress on Twitter each day.
The last photo gallery shows the results. They did an amazing job. This is definitely a try again next year project.
