1. 1. Lesson 33: From Equations to Inequalities Date: 5/19/14 346 © 2013 Common Core, Inc.

NYS COMMON CORE MATHEMATICS CURRICULUM 6•4Lesson 33 Lesson 33: From Equations to Inequalities Student Outcomes  Students understand that an inequality with numerical expressions is either true or false. It is true if the numbers calculated on each side of the inequality sign result in a correct statement and false otherwise.  Students understand solving an inequality is answering the question of which values from a specified set, if any, make the inequality true. Classwork Example 1 (8 minutes) Students will review their work from Lesson 23 and use this throughout the lesson. Example 1 What value(s) does the variable have to represent for the number sentence to be a true statement? What value(s) does the variable have to represent for the number sentence to be a false statement? a. 𝒚 + 𝟔 = 𝟏𝟔 The number sentence is true when 𝒚 is 𝟏𝟎. The sentence is false when 𝒚 is any number other than 𝟏𝟎. b. 𝒚 + 𝟔 > 𝟏𝟔 The number sentence is true when 𝒚 is any number greater than 𝟏𝟎. The sentence is false when 𝒚 is 𝟏𝟎 or any number less than 𝟏𝟎. c. 𝒚 + 𝟔 ≥ 𝟏𝟔 The number sentence is true when 𝒚 is 𝟏𝟎 or any number greater than 𝟏𝟎. The sentence is false when 𝒚 is a number less than 𝟏𝟎. d. 𝟑𝒈 = 𝟏𝟓 The number sentence is true when 𝒈 is 𝟓. The number sentence is false when 𝒈 is any number other than 𝟓. e. 𝟑𝒈 < 𝟏𝟓 The number sentence is true when 𝒈 is any number less than 𝟓. The number sentence is false when 𝒈 is 𝟓 or any number greater than 𝟓. f. 𝟑𝒈 ≤ 𝟏𝟓 The number sentence is true when 𝒈 is 𝟓 or any number less than 𝟓. The number sentence is false when 𝒈 is any number greater than 𝟓. MP.6
