Easy Lesson Plans on Order of Operations
What? Who is Aunt Sally? When students initially learn how to add, subtract, multiply, and divide, they are taught to perform those skills using two numbers and one operation. As they progress to the next levels, they begin to see numerical expressions with more than one operation and word problems that involve multiple steps. Introduce your students to the Order of Operations - and help them memorize the "PEMDAS" or "Please Excuse My Dear Aunt Sally" acronym as early as third grade. Putting this memory into practice can be more of a challenge - so we've come up with some tips and a fun lesson plan activity for your students to drive the concept home! What is the Order of Operations, and what are some ideas for teaching it? "Order of Operations" is an essential mathematical concept covered in upper-elementary grades ( 3.OA.D.8 and 5.OA.A.1 ), middle school grades ( 6.EE.2.C ) and is continued through high school algebra and number and quantity standards. Students are expected to apply them in fractions, decimals, and positive and negative integers as well. It's important to note that this acronym can lead to a common misconception by students. Most learners seem to think that all multiplication comes before division and all addition comes before subtraction. For example: It is critical to ensure students have a strong foundation at an early stage and understand that multiplication/division, and addition/subtraction have equal priority. They should be solved in order from left to right. I find it beneficial to spend extra time demonstrating additional sample problems to the class and providing them opportunities to practice in their interactive notebooks. Agree/disagree is another great activity for this lesson. It is quick and gets the entire class involved. First, the teacher will display "agree" and "disagree" signs in two places in the classroom. Then they will post a problem on the board and ask students to move to the side of the room showing whether they agree or disagree with the shown answer of the problem. Always have students defend their point of view and how they came up with the answer. Plan This Activity for your Classroom! Students can play this game with up to three partners. Each group will need a number cube/dice, an operation cube (you can 3D print these using the VariQuest Trifecta™ 800!), a game board, whiteboard markers, and a laminated recording sheet per player. This activity can be easily differentiated by adding extra dice, switching out the dice to a 20-sided die, fraction cube, decimals cube, or challenging students to include grouping symbols, exponents, positive and negative integers in their numerical expressions. Suggestions: Plan to use this activity in your classroom? We'd love to see how it went! Post a photo on Twitter and tag @VariQuest and you could be featured in our next blog! 
"Class, what is the Order of Operations?" My energetic class of fifth graders shouted out loud, "Please Excuse My Dear Aunt Sally!"
Many use the acronym P E M D A S , or " P lease E xcuse M y D ear A unt S ally," to help them remember the Order of Operations:
1. P arentheses Perform operations within parentheses and/or other grouping symbols first. 2. E xponents Find the value of all exponential expressions 3. M ultiplication & D ivision Perform all multiplication and division in order from left to right. 4. A ddition & S ubtraction Perform all addition and subtraction in order from left to right. 
Know My Order of Operations is a game I put together to benefit multiple grade levels, meeting the needs of various learning abilities. During this game, students will solve mathematical expressions involving the four operations. They will need to choose the appropriate order in which to do operations and demonstrate their understanding of the order of operations.
