Math Order of Operation – A simple trick!

Unlock the Power of TPR: A Game-Changing Strategy for Mastering Order of Operations

When children are learning any new math concept, it’s crucial to use strategies that help them retain the information efficiently. One powerful method that has transformed math instruction is Total Physical Response (TPR). This hands-on, movement-based technique accelerates learning by connecting physical actions to mental processes.

If you’ve ever tried to teach your child a math concept by simply explaining it, you may have noticed that the information often doesn’t stick. Without meaningful engagement, children can struggle to grasp essential concepts and require weeks—or even months—of repetitive drilling before they gain proficiency.

Why Does TPR Work So Well?

Research shows that children retain information far more effectively when they actively involve their bodies in the learning process. TPR is a proven technique that links movement with memory, making complex ideas easier to grasp and retain. By engaging both the mind and body, children build deeper neural connections, strengthening their ability to recall information when it matters most.

For example, if a child associates flexing their arm like a bodybuilder with solving exponents, they’ll create a memorable link that makes the concept easier to remember during future practice and tests.

Why is the Order of Operations So Confusing?

The Order of Operations is one of the most challenging concepts for children to master. Operations are the actions we perform on numbers: adding, subtracting, multiplying, dividing, etc. The confusion arises from determining which operation to perform first.

For Example:

For Example:
3 (62 + 8) – 4 x 6
What is the proper order of operation for the problem above?

Order of Operations: A Common Math Struggle

One of the most challenging concepts for students in grades 3 through 6 is the Order of Operations. This essential skill lays the groundwork for understanding algebra, problem-solving, and higher-level mathematics. Without mastering this concept, students often feel confused and frustrated, leading to a lack of confidence in their math abilities.

Understanding Order of Operations

Order of Operations refers to the correct sequence in which mathematical operations should be performed. Operations include:

  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Parentheses
  • Exponents

Most teachers introduce this concept using the popular acronym PEMDAS:

  • Parentheses
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

While PEMDAS can be helpful, it often leads to common misunderstandings. For example, children may mistakenly believe that multiplication always comes before division and that addition always comes before subtraction. In reality, multiplication and division are equally strong, as are addition and subtraction. The correct rule is to move left to right when both appear in the same expression.

Examples of Common Mistakes and Correct Solutions

Clarifying Common PEMDAS Mistakes

When you encounter multiplication and division together, like (42 / 6 x 4)or addition and subtraction togetherlike (18 – 8 + 14),

the correct approach is to solve the problem from left to right (not based on PEMDAS order alone).

Multiplication & Division

This is wrong:

This is the correct order of operation:

42 / 6 x 4
42 / 24
1.75
WRONG!

42 / 6 x 4
7 x 4
28
CORRECT!

Addition & Subtraction

This is wrong:

This is the correct order of operation:

18 – 8 + 14
18 – 22
-4
WRONG!

18 – 8 + 14
10 + 14
24
CORRECT

The “Strongest to Weakest” TPR Strategy

Instead of relying solely on PEMDAS, I teach my students the “Strongest to Weakest” strategy. This method simplifies the process and eliminates confusion. By physically acting out each step, children create memorable mental links that make learning fun and effective.

Here’s how it works:

  • Flex your arms like a bodybuilder to represent Parentheses — Point to your head to symbolize that this is the strongest operation that always comes first.
  • Exponents, are stronger than multiplication and division, which means that they are second in strength.
  • Place your hands side by side and wave them back and forth like a pendulum to represent Multiplication & Division, which are equally strong and must be solved from left to right.
  • Finally, extend your arms weakly to your sides to symbolize the weakest of operations: Addition & Subtraction, they are done last, and when both are there they are completed solved from left to right.

This physical approach gives students an engaging way to remember the correct sequence while reinforcing muscle memory.

The video below shows an example of TPR for teaching order of operation.

 

Real-Life Case Study: How TPR Transformed Learning

In my classroom, I once worked with a fifth-grade student named Jessica who had consistently struggled with the Order of Operations. Despite multiple explanations and practice problems, Jessica remained frustrated and confused.

I introduced the “Strongest to Weakest” TPR method to her. During each lesson, she physically acted out each step — flexing her arms for parentheses, tapping her head for exponents, and waving her arms for multiplication and division. Within two weeks, Jessica’s scores jumped from 42% to 88% on her math assessments. Not only did her understanding improve, but her confidence soared as well. Jessica even began demonstrating the strategy to her classmates, which further solidified her skills.

Why TPR is Essential for Visual and Kinesthetic Learners

Many children, especially those who struggle with traditional teaching methods, thrive with visual and hands-on strategies like TPR. By physically engaging with the material, these students bridge the gap between memorization and true comprehension. This method is particularly effective for children with ADHD, dyslexia, or other learning differences.

Supporting Learning with Online Video Tutorials

To complement the TPR method, I’ve developed step-by-step video tutorials for students to follow along with. These videos allow children to practice their math skills at their own pace, pausing as needed to reinforce their understanding. Every lesson breaks down concepts with clear visuals, helping students build confidence one step at a time.

  1. This blog will help kids or parents understand the way how to do pemdas, and the order of operations. So in my opinion this blog is great.

  2. I liked the part were you talked about the PEDMAS because i sometimes forget what it means but now it makes more sense. I also sometimes have trouble doing the math but now I understand a little more how to do the math.

  3. I am glad for this blog because sometimes I mess up with pemdas and do either multiplication before devision or addation before subtraction so this really helps!!!

    1. Hey JO –
      Yes – as a matter of fact, I had a 6th grade student make the addition before subtraction mistake (the one that I explain in the video) today in class. It was very timely for me, because I had recently posted this very article.
      Thanks again & have a super day!

  4. I like the part about PEMDAS, because I forget about that and now I remember it.
    Thanks for showing me “Strongest to Weakest”.

  5. This is great!!!
    Its important to remember when you get to the point in addition and subtraction to read from left to right, and your strategy really makes that clear.

  6. Never knew that PEMDAS was misleading.

    Guess that was one of the reasons why I screwed up on a test before, so thanks for the clarification.

    1. Hi 2-D
      Yes – if you follow ALL of the directions that go with PEMDAS, it does say to go left to right for multiplication and division and addition and subtraction. However, most people forget that part. I have even seen teacher who forget that critical part.
      When I teach Strangest to Weakest – kids get it, because multiplication and division and addition and subtraction are equal in strength, so they remember to go left to right.
      Thanks for sharing.
      Have a great day!

  7. You are so right with what you said about PEMDAS.
    I like your method of “strongest to weakest” better. It is awesome!
