Do your pupils truly understand inverse operations, or is their understanding a little backward? Scholars learn the meaning of an equation in the second lesson plan of a four-part Algebra series. A series of activities begins with an analysis of equality using a balance and develops into solving equations using reverse operations and modeling with equations.
