The Ratio Design Challenge is an online, interactive tool designed to engage middle school students in developing an understanding of ratio and proportional reasoning while highlighting the value of math in real-world situations and careers.
The interactive tool enables the student user to construct scale designs of an architectural venue by applying ratio/proportion calculations. Each word problem includes a guiding hint if a student answers incorrectly, and after several tries, an explanation of the correct answer will display. Critical-thinking reflection questions at the end of the user experience will challenge students to draw overarching conclusions about the math concepts and to reflect on the real-world implications.
The interactive tool has three stand-alone modules, each with a different venue theme:
Each theme of the tool can be used for whole-class instruction, independent practice, and/or homework. A Using the Tool page is included to help students extend their thinking about ratio concepts.
The interactive tool supports both the Common Core State Standards for Mathematics (including Practice Standards) as well as the National Council for Teachers of Mathematics (NCTM) Principles and Standards, both at the middle school level.
