This article highlights a collaborative project between first- and third-grade students who built mobile apps to teach mathematics concepts to kindergartners, providing an easily replicable framework within which students lead the way through a STEM design challenge. iSTEM (Integrating Science, Technology, and Engineering in Mathematics) authors share ideas and activities that stimulate student interest in these integrated fields in K–grade 6 classrooms.
