A snowman appears overnight that nobody remembers building, and 2nd grade, 3rd grade, 4th grade and 5th grade students work out whose it is. Winter CSI math worksheets that play like a game hold attention far better than drill, and this mystery keeps them adding and subtracting to the last clue. Print the pages and they are ready. Students follow an addition path one step at a time, decode answers into a word with a letter key, and spot errors in worked equations before checking the suspect chart. Answer keys included.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: Who Built the Snowman?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYou wake to a freezing morning and a thick blanket of snow across the yard. School is called off, everyone is out building - and by the time the street wakes up properly, one snowman is standing where nobody remembers building one. Your class takes the case and works the clues until only one builder is left.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAddition with 2-digit and 3-digit numbers\u003c\/li\u003e\n  \u003cli\u003eSubtraction to narrow down the final clue\u003c\/li\u003e\n  \u003cli\u003eFollowing an addition path from start to finish, one step at a time\u003c\/li\u003e\n  \u003cli\u003eUsing a key to turn answers into letters and letters into a word\u003c\/li\u003e\n  \u003cli\u003eDeciding whether a worked equation is right or wrong - error spotting, not just answering\u003c\/li\u003e\n  \u003cli\u003eReading a suspect chart and matching your answers against it\u003c\/li\u003e\n  \u003cli\u003eAnswer keys included\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\u003eA CSI Mystery Detective case is a whodunit whose only clues are answers. Work the page, cross a suspect off with each correct one, and close the case on the name that survives. It runs like a math escape room that needs a printer instead of locks, an app or any setup. Ordinary math worksheets can be half-done and still look finished; detective activities cannot, because a wrong answer leaves nobody matching the description. A math activity for a lesson, for math centers, or for a sub plan.\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\u003eWinter and holiday math centers\u003c\/li\u003e\n  \u003cli\u003eThe last weeks of term before the December break\u003c\/li\u003e\n  \u003cli\u003eJanuary, when the class comes back and needs something that holds them\u003c\/li\u003e\n  \u003cli\u003eSnow days and shortened timetables\u003c\/li\u003e\n  \u003cli\u003eDecember, January and February math review\u003c\/li\u003e\n  \u003cli\u003eSub plans and emergency cover\u003c\/li\u003e\n  \u003cli\u003eEarly finishers, morning work and homework\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDesigned for 2nd grade, 3rd grade, 4th grade and 5th grade.
