{"product_id":"order-of-operations-csi-mystery","title":"Order of Operations CSI Mystery Worksheets | Grades 4–8 | The Bank Heist","description":"\u003cp\u003eOrder of operations worksheets for 5th grade with a CSI Math Detective case to solve: parentheses, brackets and braces, no exponents, and a bank vault with one cash bag missing. Students evaluate numerical expressions, spot the classic slips of working left to right or skipping the brackets, compare expressions built from the same numbers, place the parentheses to hit a target, and follow a getaway trail where every stop is a calculation. Print-and-go for math centers, morning work, early finishers, sub plans, homework and test prep in any month from September to June, and a strong order of operations activity for 4th grade extension and 6th grade review before exponents arrive. Color and black-and-white pages with answer keys, and only the right math keeps the mystery moving.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Case: The Bank Heist\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCity Central Bank locked its vault for the weekend. On Monday the door was still locked and the alarm had never sounded, but one cash bag was gone and the sheet saying which one had been soaked through.

Think of a math escape room where the locks are replaced by suspects: each correct answer rules another one out, and the case only closes when the arithmetic is right all the way through. That built-in check sets detective activities apart from ordinary math worksheets, and makes one case a complete math activity for a lesson, a center or a sub day.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMath centers and rotations\u003c\/li\u003e\n  \u003cli\u003eMorning work and warm-ups\u003c\/li\u003e\n  \u003cli\u003eEarly finishers\u003c\/li\u003e\n  \u003cli\u003eSub days and emergency plans\u003c\/li\u003e\n  \u003cli\u003eHomework and spiral review\u003c\/li\u003e\n  \u003cli\u003eTest prep before state testing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned for 5th graders learning to evaluate and write numerical expressions with grouping symbols, where the whole topic is taught.
