That makes them a good first PEMDAS activity for 5th grade, set as five CSI Mini Mystery Detective cases with math on every line. Use them in class, as homework, or as a quick check on numerical expressions. They're no prep, and each case comes with an answer key.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eEach page has 24 expressions and a list of 25 suspects. When a student solves an expression, the answer matches the number beside one suspect, and that suspect gets crossed off. The last name left is the culprit. Students can see for themselves whether their order of operations was right, without you checking every line.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Phone\u003c\/strong\u003e - a friend's phone has been stolen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Teacher\u003c\/strong\u003e - a teacher has been kidnapped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Principal's Car\u003c\/strong\u003e - the principal's car is gone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Bank Job\u003c\/strong\u003e - a bank robbery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiamond Heist\u003c\/strong\u003e - a chest of diamonds stolen\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFive one-page cases, each with 24 order of operations problems\u003c\/li\u003e\n  \u003cli\u003eParentheses with all four operations\u003c\/li\u003e\n  \u003cli\u003eWhole numbers only.
