Frequently Asked Questions

Third grade introduces the concept that multiplication and division are performed before addition and subtraction in an expression without parentheses (CCSS 3.OA). This is a precursor to the full order of operations (PEMDAS) formalized in fifth grade (5.OA.A.1). Third graders work with simple two-operation expressions to develop this foundational understanding.
