{"product_id":"3d-shapes-geometry-csi-mystery","title":"3D Shapes Geometry CSI Mystery Worksheets | Grades 1–5 | Shape Investigation","description":"\u003cp\u003e3D shapes, faces, edges and vertices, and a cube net: 2nd grade and 3rd grade geometry in one CSI Mystery Detective case, ready for March. These math worksheets have students naming solid shapes, sorting 2D from 3D and counting faces, edges and vertices while working a mystery where every witness is truthful and useless, and each correct answer crosses one suspect off the line-up. Few geometry packs end this way: the final page is a cube net to color, cut and fold into the culprit, so the answer stands on the desk. Color and black-and-white versions, answer keys, and the only prep is scissors for that last page.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: The Geometry Investigation\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThere is a shape at the center of this and the witness statements are, as usual, technically accurate and no help at all. Your students work through it in stages: decode the message, build a suspect list from the shape names, work out that whatever did it has three dimensions, and narrow it down from there until only one shape can possibly fit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eA letter-and-number cipher that decodes the opening message\u003c\/li\u003e\n  \u003cli\u003eListing and drawing as many shapes as your students can name\u003c\/li\u003e\n  \u003cli\u003eA word search that builds the suspect list - circle, cone, cube, cuboid, cylinder and the rest\u003c\/li\u003e\n  \u003cli\u003eShading the three-dimensional shapes to separate them from the flat ones\u003c\/li\u003e\n  \u003cli\u003eA final puzzle that decides between the last two suspects\u003c\/li\u003e\n  \u003cli\u003eA cube net to color, cut and fold into a character\u003c\/li\u003e\n  \u003cli\u003eFull color and black-and-white versions of every page, and answer keys\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\u003eEvery CSI Mystery Detective case is an elimination rather than a test. Students solve a page of math worksheets, each correct answer rules a suspect out, and the last name standing is the culprit. It is a math escape room without locks, apps or preparation. That structure is what makes detective activities self-checking - a wrong answer leaves too many suspects alive and the class can see it at once. Use it as a whole math activity, in math centers, or as something to leave a substitute.\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\u003eIntroducing or consolidating 3D shapes and their properties\u003c\/li\u003e\n  \u003cli\u003eNets and shape-building work with a reason behind it\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\u003eBack-to-school weeks and end of year review\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 2nd grade and 3rd grade.
