Unit 3, Lesson 5# Using the Identity and Inverse to Write Equivalent Expressions

EngageNY 45 min(s)

Students recognize the identity properties of 0 and 1 and the existence of inverses (opposites and reciprocals) to write equivalent expressions. Students work independently to rewrite numerical expressions recalling the definitions of opposites and reciprocals. The sum of a number and its additive inverse is equal to zero.
