iSTEM: Integrating Science Technology Engineering in the Mathematics authors share ideas and activities that stimulate student interest in the integrated fields of science, technology, engineering, and mathematics (STEM) in K'grade 6 classrooms. In this month's lesson, elementary school children in the primary grades learn to create symmetrical structures using wooden blocks. Student interviews and an observational rubric are used to assess the children. Extensions for intermediate elementary grades are provided.

This month, students are presented with a scenario in which two friends must decide how to cut a cake so they each get the same amount. Students will use transformations and their spatial reasoning to determine various ways to cut the cake. Each month, elementary school teachers receive a problem along with suggested instructional notes and are asked to use the problem in their own classrooms and submit solutions, strategies, and reflections to the journal.
