In this Working Group (WG), we explored the opportunities and challenges of teaching and learning mathematics in an interdisciplinary (I-D) context. To follow Staats (2014) this means �drawing a context from another discipline authentically enough to support learning in both disciplines� (p. 7), mathematics plus the �other�. While the notion of interdisciplinarity is not new, contemporary promotion of STEM/STEAM, new mathematics curricula in which the �focus is on real-life, relevant contexts� (BC Math Curriculum, 2018, para. 9), and ongoing efforts to foster mathematical literacy (OECD PISA, 2019) made this a timely focus for a CMESG working group.
