{"product_id":"solving-absolute-value-equations-mystery-detective","title":"Solving Absolute Value Equations | Mystery Detective | Grades 6–9 | Grand Hotel","description":"\u003cp\u003eSolving absolute value equations worksheets, Algebra 1 practice pages, and self-checking Mini Mystery Detective pack of math activities for 8th grade, 9th grade and 10th grade are all included in this printable detective pack. Students isolate the absolute value, split each equation into its two cases and find both values of x - working through equations with a coefficient outside the bars, a term to undo first, and a coefficient inside the bars where the solutions turn into fractions. Perfect for math centers and stations, guided math and small groups, warm ups and bell ringers, homework and independent practice, spiral review, test prep, intervention, tutoring, enrichment, early finishers, substitute plans and homeschool. Completely no prep - just print and go.\u003c\/p\u003e\n\u003cp\u003eEvery case is set in one grand old hotel: a leaking top floor, a stopped hall clock, a spoiled banquet, a drained roof pool. Because every equation here has two solutions, a student who drops the negative case cannot finish the mystery - the pages check themselves, so students go back and find their own mistake before it ever reaches your marking pile.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSplitting an absolute value equation into its two cases: |x - 26| = 36\u003c\/li\u003e\n  \u003cli\u003eDividing by a coefficient before the split: 7|x - 18| = 105\u003c\/li\u003e\n  \u003cli\u003eUndoing a term outside the bars first: |x - 25| - 16 = -8\u003c\/li\u003e\n  \u003cli\u003eTwo moves before the split: 3|x + 8| + 12 = 45\u003c\/li\u003e\n  \u003cli\u003eA coefficient inside the bars, where the solutions become fractions: |4x - 5| = 29\u003c\/li\u003e\n  \u003cli\u003eA coefficient inside and a term outside together: |5x - 15| - 12 = -4\u003c\/li\u003e\n  \u003cli\u003eWriting both solutions, positive and negative, in simplest form\u003c\/li\u003e\n  \u003cli\u003eA reference page on when an absolute value equation has two solutions, one solution, or no solution at all\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTen leveled cases run through the Grand Meridian hotel: The Leaking Top Floor, The Silent Room Phone, The Missing Roof Key, The Stopped Hall Clock, The Cold Dining Room, The Torn Floor Map, The Spoiled Banquet, The Switched Bag Tags, The Drained Roof Pool and The Blank Lobby Screen.\u003c\/p\u003e\n\u003cp\u003eAnswer keys, a detective's case log and a certificate of achievement are included.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA no-prep detective activity where students solve math problems to cross off suspects and unmask the culprit.
