{"product_id":"rigid-transformations-mystery-detective","title":"Rigid Transformations | Mystery Detective | Grades 7–9 | Archive Files","description":"\u003cp\u003eThese rigid transformations worksheets are ten 8th grade math Mini Mystery Detective cases on translations, rotations and reflections. In every case a forger has slid, flipped or turned a shape, and students use the matching letters to find the side lengths, angles, perimeter and parallel sides of the copy, which is exactly what the 8.G.A.1 standard asks them to verify. It is transformations practice for your geometry unit that works as math centers, bell ringers, homework or test prep, with answer keys included - just print and go.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eRight after you introduce translations, reflections and rotations is when this pack fits best. Students discover for themselves that a copy keeps every length and every angle, because they have to match A to A' to find each answer. Each page puts two different moves side by side, so a flip and a turn are compared on the same sheet, and every CSI Mini Mystery Detective page is self-marking.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTen one-page forgery cases, each with two shapes and their copies and 20 questions, and an answer key for every case\u003c\/li\u003e\n  \u003cli\u003eTranslations, reflections and rotations of trapezoids and pentagons, drawn to scale\u003c\/li\u003e\n  \u003cli\u003eQuestions on matching sides, matching angles, the perimeter and which side stays parallel\u003c\/li\u003e\n  \u003cli\u003eA transformations reference page showing a slide, a flip and a turn, and what stays the same\u003c\/li\u003e\n  \u003cli\u003eA contents page, teacher instructions, a detective case log and a certificate of achievement\u003c\/li\u003e\n  \u003cli\u003e30 black and white pages, ready to print\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Forged Vault Key\u003c\/strong\u003e - a copied key tag and bow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Cloned Bank Card\u003c\/strong\u003e - a fake chip and hologram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Copied Police Badge\u003c\/strong\u003e - a traced badge and crest\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Frozen Camera Feed\u003c\/strong\u003e - a pasted window and doorway\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Cloned Door Pass\u003c\/strong\u003e - a fake pass and keypad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Stolen Drone Plans\u003c\/strong\u003e - a turned wing and tail fin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Planted Fingerprint\u003c\/strong\u003e - lifted prints on glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Cracked Safe Code\u003c\/strong\u003e - copied dial and hinge plates\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Swapped Archive Files\u003c\/strong\u003e - fake file tabs and clips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Silenced Alarm\u003c\/strong\u003e - a flipped sensor plate\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUse these cases once students have seen the three rigid transformations and are ready to prove what each one keeps the same. Every page asks for lengths, angles, the perimeter and a parallel side, so students practice all three parts of 8.G.A.1 on every sheet. The measurements are split between the original and the copy, so students work in both directions, from the shape to its image and back again, which builds the habit of matching corresponding parts before the congruence lessons. Every case stands on its own, so you can use one a day across two weeks or give different cases to different groups. It works well for math centers and stations, bell ringers, homework, small group work, sub days, test prep, early finishers and end of year 8th grade geometry review.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWritten for 8th grade (8.G.A.1, properties of rotations, reflections and translations).
