Instructional sequence for multidigit multiplication in base five
Page: 507
In this poster I describe an instructional sequence for supporting the guided reinvention of multidigit multiplication in a preservice teacher content course. I use design heuristics from Realistic Mathematics Education (Gravemeijer, 1998) to design, test, and modify an instructional sequence leveraging the non-routine context of base five.
