The lesson study process included preparing, observing, and critiquing mathematics lessons in the context of solving fractions tasks. By conducting the lesson study, the authors anticipated that these teachers would develop greater insight into students\rq mathematics, which would influence their classroom practices. Through the process of planning, observing and critiquing and by purposefully listening to students\rq explanations, the teachers began to better understand their students\rq learning, which in turn could help them develop their students\rq mathematical knowledge. rv:
