## mentor interview

In this reflection, Mia Buljan observes how she seeks to understand her students’ development as young mathematicians, laughing that “a seven year old is a very imprecise tool to do math with!” She connects that developmental perspective to her teaching of the mathematical practices. She calls out how, for example, the mathematical practices 7 and 8, are “more mathy” because they are about identifying patterns and expressing regularity in reasoning. Her challenge is not to encourage students to identify patterns, but to recognize that not all of their patterns or rules may be mathematically sound; her job is to find problems or scenarios that require her students to test their thinking about their patterns and assumptions.
