6.EE.B.6: Reason about and solve one-variable equations and inequalities. TEACHER: Terri Pemberton SUBJECT: 6th Grade Math STANDARD: 6.EE.B.6 - Use variables to represent numbers and write expressions when solving a realworld 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. STUDENT TARGET: Use a variable to write an algebraic expression that represents a real-world situation when a specific number is unknown. Explain and give examples of how a variable can represent a single unknown number or can represent any number in a specified set. EVIDENCE OF MASTERY (MEASURABLE): SUB-OBJECTIVES: SWBAT use a variable to write an algebraic expression that represents a real-world situation. KEY VOCABULARY: variable, constant algebraic expression MATERIALS: 15 copies of matching game handout http://www.engageny.org/sites/default/files/r esource/attachments/math-g6-m4-teachermaterials.pdf pgs 257-258 15 baggies (1 per group) Scissors (1 per student) DURING BEFORE ENGAGE (MAKE CONTENT AND LEARNING RELEVANT TO REAL LIFE AND CONNECT TO STUDENT INTEREST) TEACHER WILL: STUDENT WILL: Ask students to brainstorm, as a review, the Brainstorm the meaning of variable, constant meaning of variable, constant and algebraic and algebraic expression and be ready to share expression. with the class. Show students the following algebraic T-P-S what the equation x + 4 =100 could expression and ask them to T-P-S what they represent in a real-world situation. think each term could represents. x + 4 = 100. TEACHER WILL: Hand out copies of matching game, baggie and scissors to each pair of students. (do this only with the first group of students, then use for the rest of the blocks) Instruct students to cut out game pieces and begin matching the equation to the solution. Tell students that they will need to create a real-world scenario for each equation and be prepared to share with the class. STUDENT WILL: Cut out game pieces and begin matching the equation to the solution. With partner, using words, create a real-world scenario in which each equation could be used and be ready to share with the class. AFTER 6.EE.B.6: Reason about and solve one-variable equations and inequalities. TEACHER WILL: Bring students back together and ask them to share some of their real-world scenarios. Handout “Pandas Pizza Place” worksheet (attached) and tell students to create an equation for each word problem. Tell them they also have to create an additional equation for a scenario that has not been given. STUDENT WILL: Share some of their real-world scenarios. Complete “Pandas Pizza Place” worksheet. 6.EE.B.6: Reason about and solve one-variable equations and inequalities.
