Reflection: Staircase of Complexity Roll a Subtraction Problem - Section 6: Exit Ticket

Understanding a process is important, but if a student doesn't understand why the process works, it's pointless. When students get to algebra they struggle unless they have a conceptual understanding of how and why the processes work.

It is our responsibility as educators to provide the experiences, support and challenges that encourage that kind of internalization of concepts. Building on prior knowledge and creating a staircase of complexity in solving these types of problems builds the bridge needed for kids to confidently understand the concepts behind the math.
