The document provides instructions for a three-session lesson plan on multiplication for third grade students. In session one, students will watch videos on solving multiplication using repeated addition and arrays. They will take notes and discuss what they learned. In session two, students will watch another video on arrays, take more notes, and discuss. In session three, students will write an explanation of what they know about multiplication based on what they learned from the videos and class discussions. The teacher will score the student writing using a rubric.
