This is a Common Core Exploration that involves architectural remodeling and decimal / equivalences.
This is two-class period a PBL type project. Your students will research and draw their model (of famous structural buildings or bridges) on Day One and build the model on Day Two. You are given the Saint Louis Arch to model for them -- all answers and pictures of a scaled model are included.
Common Core Standards:
Draw construct, and describe geometrical figures and describe the relationships between them. » 1 Math Standard • www.corestandards.org/Math/Content/7/G/A/1/ ...a scale drawing and reproducing a scale drawing at a different scale. Analyze proportional relationships and use them to solve real-world and mathematical problems. » 2 Math Standard • www.corestandards.org/Math/Content/7/RP/A/2/ Recognize and represent proportional relationships between quantities, in this case decimal equivalency. ELA Standard • www.corestandards.org/ELA-Literacy/CCRA/W/7/ Conduct short as well as more sustained research projects. ELA Standard • www.corestandards.org/ELA-Literacy/CCRA/W/ ...to build knowledge on a subject through research projects
