Students solve equations with one variable across addition, subtraction, multiplication and division, so the pack covers the whole one step unit as algebra math activities and self-checking practice. Year round, with no season attached, for test prep, math centers, early finishers, homework, morning work and sub plans, and a full answer key for every case.\u003c\/p\u003e\n\n\u003cp\u003eThe first week of algebra is where students decide whether solving for x is a puzzle or a chore, and a suspect lineup tips it towards puzzle. Every equation they undo points at one name, so the whole class stays with the page and checks its own inverse operations without being told to. Use a CSI Mini Mystery Detective math case with everyone after the lesson, then keep the rest for small groups and early finishers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Car Keys\u003c\/strong\u003e - gone from the rack overnight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSnuggles\u003c\/strong\u003e - the neighbor's pet has vanished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Phone\u003c\/strong\u003e - it disappeared between classes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Art Gallery Heist\u003c\/strong\u003e - a masterpiece walks out the door\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Bank Robbery\u003c\/strong\u003e - someone cleaned out the vault\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFive case files, each one a crime sheet of equations with its own lineup of suspects\u003c\/li\u003e\n  \u003cli\u003eOne step equations with a single variable, across adding, subtracting, multiplying and dividing\u003c\/li\u003e\n  \u003cli\u003eWhole number answers, so no fractions or decimals slow the solving down\u003c\/li\u003e\n  \u003cli\u003eEvery answer matches one suspect and no other, so the page checks itself\u003c\/li\u003e\n  \u003cli\u003eA full answer key for every case\u003c\/li\u003e\n  \u003cli\u003ePrint and go: no cutting, no laminating, nothing to set up the night before\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA CSI Mini Mystery Detective gives your class a crime, a lineup and a page of questions, and the only route to the culprit runs through the math. Each suspect wears a number, each correct answer matches one of them, and that name is struck off until a single suspect is left. Because a wrong solution rules out the wrong person, these detective activities push students to check their work in a way math worksheets do not.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eUse this once your class has met inverse operations and can solve for a variable in one move, either as the practice day straight after you teach it or as the review before the unit test. It fixes the thing every equations unit runs into: students who can do the math but will not stop to check the answer they wrote. Here a wrong solution crosses off the wrong suspect, so they catch the slip themselves before you grade a page.\u003c\/p\u003e\n\n\u003cp\u003eTeachers use these case files for test prep, homework, math centers, morning work, early finishers, sub plans and homeschool lessons, with a whole class, a small group or one student alone.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eWritten for 6th grade and 7th grade, where one step equations sit in the standards.
