A discussion group met and discussed the current state of research in the domain of integers at the joint PME 38 and PME-NA 36 meetings (Bofferding, Wessman- Enzinger, Gallardo, Salinas, & Peled, 2014). During these meetings productive discussion revolved around what it meant to understand integers. Additionally, the organisers presented a literature review of the research on integers from all of the PME and PME-NA proceedings, which the group discussed. At the conclusion of this meeting, the group expressed interest in investigating integers further together by pursuing an international curriculum comparison study. This working group aims to begin this curriculum comparison study of integers.
