1 Eureka Math Module 4 Topic G Solving Equations Lessons EE.B.5 Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. 6.EE.B.7 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
2 Vocabulary Numerical Expression a statement consisting of and Algebraic Expression a statement consisting of,, and Number Sentence - a statement of equality (or ) between two numerical. Equation a number sentence that states two are. Inequality a number sentence that states two are. Variable a letter that represents an amount Coefficient a number attached to a in a expression Constant a number that in a number sentence Inverse Operation the operation

4 Lesson 24 True and False Number Sentences Standard: 6.EE.B.5 Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. Objective: I can write and symbols to determine if a number sentence is or. Guiding Question: What is the difference between an equal sign and inequality symbols.
5 Lesson 24 True and False Number Sentences Mastery of the Objective To master the objective, you should be able to
6 Lesson 24 True and False Number Sentences Guided Notes! Inequality and Equality Symbols Symbol Phrase Meaning Example < is less than a < 5 > is more than b > 5 is at least b 5 is at most a 5 = is the same as a = 5
7 Lesson 24 True and False Number Sentences Steps substituting variables and evaluating expressions 1. Rewrite the expression 2. Substitute the variable 3. Solve
8 Lesson 24 True and False Number Sentences Examples!
9 Lesson 24 True and False Number Sentences Examples! What does this symbol mean?
10 Lesson 24 True and False Number Sentences Examples! Steps! 1. Figure out what the variable is EQUAL to. 2. Substitute the value into the equation or inequality 3. Write the variable as an equation or inequality 4. Express the equality or inequality in words.
11 Lesson 24 True and False Number Sentences Closure! 5 + x = 8 Substituting 3 for x in the above number sentence made the number sentence true. What number can we substitute for a in 4a 16 to make the number sentence true? What values would make the number sentence false?
