This Instructional Activity is a part of the Lesson 12, Unit 1, Grade 6. After making an estimate of the number of sticky notes on a cabinet in the warm-up, students now brainstorm ways to find that number more accurately and then go about calculating an answer. The activity prompts students to transfer their understandings of the area of polygons to find the surface area of a three-dimensional object. Students learn that the surface area of a three-dimensional figure is the total area of all its faces.
