Teaching Order of Operations: No-fail Strategies that Really Work!

Order of operations can be frustrating to teach, but it doesn't have to be. There's no question that this is an extremely challenging topic for elementary students. Fortunately, there are loads of strategies for teaching order of operations that are both fun and effective.

One reason kids struggle with this concept is that there are so many rules to learn and follow. Even worse, rules that appear to be simple often prove to be deceptively complex.

For example, most kids can easily remember that multiplication and division are always performed before addition and subtraction, especially after they learn to follow the order described by "PEMDAS."

However, they tend to get stuck when an equation includes both multiplication AND division. Most kids automatically multiply before dividing, but order of operations tells us to perform the operation that comes first when reading the problem from left to right. No wonder kids find order of operations to be super confusing!

Another reason kids struggle is that even when they understand how to use order of operations correctly, they don't apply the rules systematically. Because the problems look easy, students try to rely on mental math alone to solve them. This may work with the easy problems, but mental math isn't effective with more complex problems that include multiple operations, parentheses, exponents.

After watching my students struggle with order of operations, I developed a simple lesson that worked every time. As a result, my students actually remembered the rules and could easily apply them to any problem. I'd like to share these no-fail strategies with you, along with two free order of operations printables you can use to help your students grasp these concepts.
