Abstract	In this article, the authors share the potential for two types of atypical arrays (composite and partially hidden) to stimulate initial multiplicative ideas and strategies from students in a second-grade classroom. Composite arrays are defined here as nonarrays that are composed of multiple smaller complete arrays. The atypical arrays were presented to the students after an array unit on complete arrays. The composite and partially hidden array tasks were given as quick images (each image was displayed for about 8-20 seconds) during a 25-minute routine, with about three or four images shown per routine. During the think-pair-share time, the teacher gathered various strategies that students were sharing in pairs. This was followed by a whole-class discussion, with the teacher first asking students to share the numbers they got, then having some explain their strategies (while showing the image a second time), and recording those on the board. This article shares the benefits of using atypical arrays and the how the classroom set up gave each student ownership of their solution strategies, the chance to learn from their classmates, and the opportunity to try new strategies.
