**Often people are faced with the task of arranging furniture to use the space in a room efficiently. For the design challenge at the end of this unit, students will be asked to do exactly that in their own classroom. To prepare for the challenge, students will be learning how to compare the sizes of different objects against each other. They will learn about measuring different attributes, including length, width, and measuring with different units such as inches and centimeters.**

**Educational outcomes**

**Students will be able to compare measurable attributes of different objects.**- Students will be able to compare the strengths and weaknesses of various measuring tools.

**STEAM INTEGRATION**

Once students have enthusiasm and curiosity towards measuring, inspired by the empathy lesson, they will explore measuring with both standard and non-standard tools. Lesson 3 gives students the opportunity to compare objects with a measurable attribute in common, to see which object has more or less of the attribute (K.MD.A.2). In lesson 4, students will inspect measuring tools to compare the strengths and weaknesses of how each performs (K-2-ETS1-3) to inform their design of a measuring tool in the design challenge.
