{"product_id":"adding-subtracting-integers-csi-mystery-zombie","title":"Adding \u0026 Subtracting Integers CSI Mystery Worksheets | Grades 6–9 | Zombie Outbreak","description":"\u003cp\u003eHalloween adding and subtracting integers for middle school, grade 6, grade 7, grade 8 and grade 9, in a CSI Mystery Detective case where the zombie outbreak started at school. Positive and negative numbers identify the culprit: how fast it moves, how much it smells and how many brains it gets through come down to integers, and one zombie outside used to be someone your students knew. Math worksheets print in color or black and white with answer keys; October needs only a stapler. Students carry a running total along a path, color the correct arrow, decode secret messages from their answers and rule out suspects until one description fits and the mystery ends.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: Run Zombies Run\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe outbreak started at school. Friends, family and teachers have all gone the same way, and the survivors have barricaded themselves into what is left of the building. One of the zombies outside used to be someone your students knew. Working out which one means working the integers - how fast it moves, how much it smells, how many brains it gets through - until only one description fits.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAdding and subtracting integers along a path where the running total settles the clue\u003c\/li\u003e\n  \u003cli\u003ePositive and negative number problems that color the correct arrow forward\u003c\/li\u003e\n  \u003cli\u003eDecoding a secret message from integer answers\u003c\/li\u003e\n  \u003cli\u003eChecking worked integer problems for errors and tallying the results\u003c\/li\u003e\n  \u003cli\u003eA second decoding page built on adding and subtracting negative numbers\u003c\/li\u003e\n  \u003cli\u003eFull color and black-and-white versions of every page\u003c\/li\u003e\n  \u003cli\u003eAnswer keys for the whole case\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\u003eStudents are the detectives and math is the only evidence they are handed. That is the whole of a CSI Mystery Detective case: work the page, rule a suspect out with every correct answer, close the case on the last name standing. It runs as a math escape room with no locks, no app and no prep. It is also self-marking in practice, which ordinary math worksheets are not - a wrong answer produces a culprit who cannot exist. Use it as a math activity, in math centers, or as 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\u003eInteger review before or after a unit test\u003c\/li\u003e\n  \u003cli\u003eHalloween week in October, when a normal worksheet will not hold them\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\u003eEnd of year review, when attention is thin and the work still has to happen\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 grade 6 and grade 7, and it holds up for grade 8 and grade 9 students who need integer review.
