ab: Summary: When finding the decimal equivalent of a fraction with 12 in the
denominator, will it terminate or repeat? This question came from a
seventh grader in author Erica Burnisonâ€™s class as the student was
pondering a poster generated by one of her classmates. Not only was the
question intriguing, but it also affirmed the belief in the power of
tailoring instruction to studentsâ€™ interests and needs. As math
educators, trying to figure out how to implement the content and
Standards for Mathematical Practice (SMP) found in the Common Core
State Standards for Mathematics in a student-centered fashion, the
authors were thrilled by this moment. This question from a student also
demonstrated that students can engage in the SMP while working in
collaborative groups. In this article, the authors will describe the
activities that gave rise to this student-generated question. They will
also provide their collaborative reflection of the activities because
they find that collaboration deepens their understanding of pedagogy as
well as mathematics. The authors hope that their account will inspire
others to work together. (ERIC)
