The witnesses agree the number has three digits and is a small one, which still leaves a room full of suspects, so this mystery number case doubles as a 4th grade math review and a winter math activity. Color and black-and-white copies of every page are in the file, so it prints and goes. Students decode the opening cipher, build the line-up from the witness descriptions, sort odd from even and order the numbers from smallest to biggest, sending suspects home until one number is left.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: The Suspect Number\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe witnesses are unusually cooperative for once. They are certain the number has three digits, and just as certain that it is a small one. That still leaves a room full of suspects, so your students take it further: odd or even, where it sits in the order, which numbers it lives nearest to. Each answer sends more of them home.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eA letter-and-number cipher that decodes the opening message\u003c\/li\u003e\n  \u003cli\u003eBuilding the suspect list from three-digit numbers described by the witnesses\u003c\/li\u003e\n  \u003cli\u003eSorting the suspects into odd and even numbers\u003c\/li\u003e\n  \u003cli\u003eOrdering the line-up from smallest to biggest\u003c\/li\u003e\n  \u003cli\u003eWorking out which tens and hundreds each number sits between\u003c\/li\u003e\n  \u003cli\u003eA final shading puzzle that separates the last two suspects\u003c\/li\u003e\n  \u003cli\u003eFull color and black-and-white versions of every page, and answer keys\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mystery Detective Case?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA CSI Mystery Detective case is a printable investigation your class closes with math. Each correct answer eliminates one candidate, and the case ends when a single one is left. It behaves like a math escape room minus the locks, the app and the setup - you print it and hand it out. What separates detective activities from ordinary math worksheets is that the arithmetic has consequences, so students check their own before handing it in. It carries a whole math activity, a center rotation, or a sub plan.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eOrdering and comparing numbers review before or after a unit test\u003c\/li\u003e\n  \u003cli\u003ePlace value work that is not another page of columns\u003c\/li\u003e\n  \u003cli\u003eMath centers, early finishers and independent work\u003c\/li\u003e\n  \u003cli\u003eEmergency sub plans that run themselves\u003c\/li\u003e\n  \u003cli\u003eBack-to-school weeks and end of year review\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eBuilt for 3rd grade, 4th grade and 5th grade.
