Next, students used Scale City videos and interactive tools to learn more about how scale and proportion are used in real life tourist attractions in Kentucky. From scaling two dimensional murals to scaling recipes at the World Chicken Festival, this site provided engaging content and cross-curricular connections. |
Students in 7th grade math used technology throughout the unit on scale and proportion. The unit began with a discussion about how people use scale in every day life. We discussed how movie makers use scale models, engineers and architects use scale to create construction drawings, and toymakers use scale to make adult sized objects just right for children. For the first activity, students measured simple geometric objects and created them in Sketchup at their original size and then smaller or larger based on a random scale factor. Students shared their Sketchup drawing in a shared Google folder, and then downloaded one of their peer's drawings to determine their scale factor. For the final project for the scale and proportion unit, students chose to create a scaled version of famous landmarks, everyday objects or areas of school. Working in teams, students could choose to create a scale model, diorama or 3-D drawing of their object. Some of the students who chose to create their object in Sketchup or Tinkercad will have their object printed on the high school 3-D printer. Scale and proportion are a big part of our everyday lives in many ways. This unit provided hands-on and tech-on opportunities for students make connections and apply proportional thinking.

Looks like a great project. The photos really make the difference in being able to imagine what it looked like in the classroom.
