Investigating Using Lesson Study

Our middle school mathematics department used lesson study to investigate how to introduce fractions division to our sixth-grade students. We highlight our learnings during the Study and Plan phases, describe our observations during the lesson, and provide tips for educators interested in using lesson study to study their own content.

Footnotes

Middle school teachers offer tips for educators by highlighting what they learned and observed in introducing fraction division.
