Art is about thinking. It requires persistence and a willingness to explore many options for solving problems. These are not quantifiable measurements but, more significantly, they rely on students' increasing development of the ability to learn through exploration, experimentation, self-questioning, and self-assessment. Using paper, scissors, and glue, students can invent ways to communicate their ideas while they solve a variety of three-dimensional engineering problems. Paper can be made to stand up, bend, fold, and connect. In this lesson, fifth-grade students synthesize strategies that they have been discovering since kindergarten about the properties of paper. The whole class collaborates on the construction of an amusement park. (Contains 1 online resource.)
