Completely no prep math activities for math centers, morning work, early finishers, homework and sub plans, print and go with answer keys for every page. One download holds the five cases in inches and feet, the same five again in centimeters and meters, a full black and white set, and a color in page for whoever finishes first.\u003c\/p\u003e\n\n\u003cp\u003ePerimeter lands in the middle of the geometry unit, and this is the set to hand out once the rule is taught and a class simply needs the reps. A correct measurement knocks a clue out, so the page tells a student how they are doing before it tells you. Having both measurement systems in the one file means the same five cases work whichever units your curriculum uses.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMystery Chocolates - who left the box\u003c\/li\u003e\n  \u003cli\u003eShowing Mindfulness - a secret kind deed\u003c\/li\u003e\n  \u003cli\u003eMissing Shapes - the teacher's shapes vanish\u003c\/li\u003e\n  \u003cli\u003e2D and 3D Shape Songs - a singer nobody saw\u003c\/li\u003e\n  \u003cli\u003eMissing Library Book - the book never came back\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFive color case pages, twelve shapes to measure on each\u003c\/li\u003e\n  \u003cli\u003eThe same five cases again in centimeters and meters\u003c\/li\u003e\n  \u003cli\u003eEvery case a second time in black and white\u003c\/li\u003e\n  \u003cli\u003eAn answer key for every case, both unit sets\u003c\/li\u003e\n  \u003cli\u003eA color in page for early finishers\u003c\/li\u003e\n  \u003cli\u003eA teacher instruction page, print and go with nothing to prepare\u003c\/li\u003e\n  \u003cli\u003eTriangles, squares, rectangles and irregular shapes throughout\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\u003eOne printed page holding one crime and the clue list that solves it.

It suits a whole class, a small group, or the two or three who have finished everything else, and the answer keys mean it marks itself. Because both measurement systems sit in the one download, it also covers a class that meets metric in one unit and customary in another. Use it for math centers, morning work, early finishers, homework, sub plans and homeschool lessons.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eWritten for 2nd grade, 3rd grade and 4th grade.
