Unit 4, Lesson 23

True and False Number Sentences

EngageNY 45 min(s)

Students determine if a number sentence is true or false based on the given symbol. For students to be prepared to solve equations later in this module, it is important that they understand truth values in number sentences and in equations. Later, in Lesson 26, students learn why number sentences play a fundamental role in understanding both equations with unknown numbers and solution sets of equations that contain variables. Just substitute the number into the variable; then, check to see if the resulting number sentence is either true or false.
