Equation to solve: (98 2) x = 4.With Siri and Alexa becoming our new (albeit inanimate) best friends, “Please Excuse My Dear Aunt Sally”, now in its run at the Odyssey Theatre is both timely and innovative. Equation to solve: = Multiplication/Division: Addition/Subtraction: Equation to solve: 81 (9 3) = Multiplication/Division: Addition/Subtraction: Equation to solve: 56 - (9-8) 2 x = Multiplication/Division: Addition/Subtraction: Equation to solve: (95 5) - 18 = Multiplication/Division: Addition/Subtraction:Ĥ Reproducible 4 Solve the equations below by correctly following the order of operations. Equation to solve: (4 x 5) 14 2 = Multiplication/Division: + = Addition/Subtraction: = Equation to solve: (9 + 11) = Multiplication/Division: + 12 = Addition/Subtraction: = Answer: Equation to solve: x 2 2 = x = Multiplication/Division: + = Addition/Subtraction: = Answer: Equation to solve: (9-5) 3-14 x 3 8 = 3-14 x 3 8 = - 14 x 3 8 = Multiplication/Division: - 8 = Addition/Subtraction: = _ģ Reproducible 3 Follow the order of operations to solve the equations below.
Use the acronym above to help you along the way. Example: (12 4) + 6 x 2 1 = x 2 1 = none, so skip this operation My Dear: = Aunt Sally: 14 = Answer: 14 Reproducible 1 Please Excuse My Dear Aunt Sally All activity guides can be found online:Ģ Reproducible 2 S o l ve the following equations in the correct ord e r. Students should follow this order each time they solve a problem with multiple operations, simply omitting the steps that do not apply to the equation they are solving. Be sure to explain to students that not all problems will include every operation. In this example, the pink arrows mark the addition step ( = 338), while the orange arrow denotes the subtraction (338 3 = 335). Aunt Sally demonstrates that addition and subtraction should be computed during the final step of the process and, similar to My Dear, they should be calculated in the order (left to right) in which they appear. The darker purple arrows illustrate that multiplication is being computed (64 x 5 = 320), while the lighter purple arrows show that division is occurring (6 2 = 3). This acronym does not imply that multiplication should always be done before division. Stress that multiplication and division are part of the same step, and they should be computed in the order (left to right) in which they appear. Next, tell students that the My Dear words of the acronym indicate that multiplication and/or division are included in the next step of the process. Mention that the blue arrow indicates that we are now computing 4 3, which equals 64. Explain to students that if exponents are included, they are always computed next in the process. Point to the second word of the acronym, Excuse = Exponents. Draw students attention to the green section of the poster, and explain how the green arrows indicate that the operations inside the parentheses are being completed (2 x 9 = 18 and 16 4 = 4). Explain to students that if a problem contains parentheses, the operations inside them are always done first. Point to the first word of the acronym, Please = Parentheses. By repeating the acronym several times throughout your lesson, you will help students to remember it.
Point to the acronym at the top of the poster and tell students that this is a common way to remember the order of operations.
