About this unit

"Module 3 consolidates and expands students’ previous work with generating equivalent expressions and solving equations. Students solve real-life and mathematical problems using numerical and algebraic expressions and equations. Their work with expressions and equations is applied to finding unknown angles and problems involving area, volume, and surface area." Eureka Math/EngageNY (c) 2015 GreatMinds.org
