3 STANDARDS EQUATIONS AND INEQUALITIES TEACHER GUIDE 6.EE.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.6 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. 6.EE.7 Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers. 6.EE.8 Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams. VOCABULARY & KEYWORDS < < > > = less than is fewer than is smaller than below value is included less than or equal to maximum at most is not more than is not greater than greater than or equal to minimum at least is not less than is not smaller than greater than is more than is larger than above value is not included equal is same COMMON MISTAKES & MISCONCEPTIONS Students may forget to flip the inequality symbol when they divide by a negative number. Students may not set up an equation or an inequality correctly based on a real-world situation. Students may struggle to solve problems because of rational number operations. Students may not use the correct inequality symbol or may not use the correct point (included or not included) when graphing their solution. Maneuvering the Middle LLC, 207

8 INSTRUCTIONS EQUATIONS AND INEQUALITIES CUT AND PASTE TO PREP Print and copy cut and paste activity for each student. Print and copy the cards for each student. Students will need scissors and glue. TO USE Students should cut the cards apart. Students should match each word problem to the equation, model, and solution or inequality, graph, and solution. Not all of the cards will be used. OTHER TIPS Have students show work on notebook paper and match their answers before gluing to avoid mistakes. This activity is flexible and can be done individually, in partners or in small groups. Maneuvering the Middle LLC, 207
