This video features a series of four third-grade lessons designed to support students as they develop a conceptual understanding of multiplication. In each lesson, students share different strategies and engage in classroom discussions, surfacing that multiplication can be interpreted as a particular number of equal-sized groups. This work is part of a school-wide Lesson Study effort focused on building TTP classroom routines.
A document outlining the planning team’s research theme, background and research on the content and standards, unit/lesson goals, and unit/lesson plan accompanies the video.
