Understanding exponential growth is a fundamental aspect of developing critical numeracy skills; however, typically, exponential growth is introduced in curricular documents to secondary students. Moreover, such introductions tend to be in the context of formal mathematical modeling, divorced from a sense of quantity. The authors argue that, given its importance, elementary-age children should be presented with opportunities to explore exponential growth patterns and to develop an appreciation for the power of this idea. In this article, the authors put forward four principles of task design that should underpin the development of such learning experiences for elementary-age children and introduce tasks that have been trialed in elementary classrooms that capture these principles.
