"Next Generation Science Standards" ("NGSS") three-dimensional learning is valuable for all students regardless of age. The "NGSS" integrate disciplinary core ideas, science and engineering practices, and crosscutting concepts, adding rigor to science teaching and learning. Though "NGSS" performance expectations begin at the kindergarten level, students can be introduced to the three dimensions prior to kindergarten. All students, including young learners, can actively engage in science and engineering practices, and everyone can benefit from learning crosscutting concepts--themes that bridge the science disciplines. Having students engage with crosscutting concepts is important because when taught in an explicit manner, crosscutting concepts "enable less privileged students, most from non-dominant groups, to make connections among big ideas that cut across science disciplines." This article describes using a 5E (Engagement, Exploration, Explanation, Elaboration, Evaluation) lesson on dinosaurs to engage three- to five-year-old students in three-dimensional learning. The lesson explores the research questions: How long were the dinosaurs from head to tail? How did their length compare to our height? This lesson teaches the mathematical construct of nonstandard measurement, meaning measuring with objects not traditionally used as measurement tools.
