This document summarizes and provides adaptations to a SmartBoard lesson plan on variables and expressions for algebra 1 students. The original lesson plan is described as explaining variables and expressions through definitions, examples shown on the SmartBoard, and having students practice converting verbal expressions to algebraic ones. The author suggests adaptations like including notes for definitions, asking students for their own definitions first, and having more student practice through games and homework. It is noted that the variety of visual, audio, and hands-on elements support universal design principles to engage all learners.
