It is the second half of the inequalities unit as self-checking math activities, because a solution that matches no suspect sends the student back to the page. No prep, print and go, full answer keys, for test prep, math centers, early finishers, homework, morning work and sub plans, any month of the year.\u003c\/p\u003e\n\n\u003cp\u003eTwo step inequalities are rarely a topic students ask for more of, and this set is the exception in most rooms because the math is the route to the culprit rather than the point of the page. Each CSI Mini Mystery Detective math case fills a period, so five of them are a week of test prep with the keys already written, and any one of them works alone as a sub plan.\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 Museum Heist\u003c\/strong\u003e - a priceless artifact is taken\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecret Battle Plans\u003c\/strong\u003e - the plans are gone from the safe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMissing Rare Plants\u003c\/strong\u003e - taken from the botanical gardens\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatue Graffiti\u003c\/strong\u003e - the city statue is covered in paint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJewelry Store Theft\u003c\/strong\u003e - the store is cleaned out overnight\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 with a crime sheet and its own lineup of suspects\u003c\/li\u003e\n  \u003cli\u003eTwo step and multi-step inequalities, solved for the variable\u003c\/li\u003e\n  \u003cli\u003eProblems where students have to flip the sign after dividing by a negative\u003c\/li\u003e\n  \u003cli\u003eEach 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 prepare\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 puts a crime, a lineup and a page of math in front of your class, and the only way to name the culprit is to get the math right. Each suspect carries a number, each solved question matches one of them, and that suspect is struck off until a single name remains. Because a wrong solution eliminates the wrong person, these detective activities push students to check their work in a way math worksheets cannot. One case runs a class period.\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 one step inequalities are secure and the class is ready for two steps, then again as the review before the algebra test. The mistake this set is built to catch is the famous one, where students divide by a negative and leave the sign facing the same way. A solution set on the wrong side crosses off the wrong suspect, so the error surfaces on the page instead of in your grading pile.\u003c\/p\u003e\n\n\u003cp\u003eIt covers test prep, homework, math centers, morning work, early finishers, sub plans, homeschool lessons and review days, with a 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 7th grade and 8th grade, where two step and multi-step inequalities sit in the standards.
