Truth Values of a Number Sentence: A number sentence that is an equation is said to be true if both numerical expressions evaluate to the same number; it is said to be false otherwise. True and false are called truth values. Number sentences that are inequalities also have truth values. For example, 3<4, 6+8>15−12, and
The lesson will introduce students to solving number sentences using trial and improvement methods. Students will practice this method by working through example number sentences as a class and doing similar exercises independently.
Number sentences are simply the numerical expression of a word problem. Example 1: Determine whether the following sentence is true or false. 12 + 12 + 12 <4 × 12. Solution: The expression on the right side of the inequality (less than) sign is 12 + 12 + 12, which is equal to 36.

Lesson 24: True and False Number Sentences Classwork Opening Exercise State whether each number sentence is true or false. If the number sentence is false, explain why. 1. 4+5>9 2. 3∙6=18 3. 32> 64 4 4. 78−15<68 5. 22 R11+12 Example 1 Write true or false if the number substituted for results in a true or false number sentence. Substitute with
