This Instructional Activity is a part of the Lesson 15, Unit 5, Grade 6. In this activity, students work with decimals by building paper boxes, taking measurements of the paper and the boxes, and calculating surface areas. Although the units are specified in the problem, students need to measure very carefully in order to give an estimate to the nearest millimeter. Next, students compare the side lengths of several paper squares and estimate what the measurements of the boxes will be once the squares have been folded.
