Students who master the order of operations at a young age have a much better chance of excelling at higher levels of math than those who don't.

Many teachers rely on teaching the order of operations using popular PEMDAS. mnemonic (and the played-out Please Excuse My Dear Aunt Sally catchphrase).

But many students fail to ever grasp a true conceptual and procedural understanding of how to correctly apply the order or operations, and PEMDAS is the likely culprit.

The following video shows you a more effective strategy for teaching the order of operations and it includes a free reference sheet and practice worksheet (keep reading to access the video and resources). The video focuses on using the GEMS mnemonic instead of PEMDAS and answers the following questions:

-Why is PEMDAS bad?

-What does GEMS stand for in order of operations?

-Why is GEMS more effective than PEMDAS when teaching order of operations?

Learning Standard: 3rd Grade Operations and Algebraic Thinking

Solve problems involving the four operations, and identify and explain patterns in arithmetic.

Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.3

Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.
