Today, elementary school teachers continue to revisit old lessons and seek out new ones, especially in engineering. Optimization is the process by which an existing product or procedure is revised and refined. Drawn from the authors' experiences working directly with students in grades K-5 and their teachers and preservice teachers, the optimizations in this article serve to inform readers of seven of their recommendations for optimizing an engineering lesson. Their goal is to provide practical methods for optimizing preparations, time on task, and the important focal points by minimizing distractions and potential engineering design misconceptions.
