This document outlines the key points from a lesson on the relationship between visual fraction models and equations. It includes steps for reviewing homework, definitions of the reciprocal and inverse of a fraction, an example of using fraction models to represent multiplication, and exercises for students to practice relating fraction models to number sentences. The student outcome is for students to formally connect fraction models to multiplication through the use of multiplicative inverses.
