Santa's Sleigh gives them a crime scene. This Christmas CSI Mystery Detective case runs on two-digit and three-digit addition and subtraction with regrouping, plus a taste of multiplication, wrapped in a North Pole mystery for 2nd grade and 3rd grade. Helpers on double shifts, a record year for good children, and days before Christmas somebody at the Pole sabotaged the sleigh. Each correct answer strikes a suspect off the line-up until one remains, from a trail of presents to a decoration colored by the right product. Print in color or black and white, answer keys included, no prep.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: Help!

That is the whole of a CSI Mystery Detective case: work the page, rule a suspect out with every correct answer, close the case on the last name standing. It runs as a math escape room with no locks, no app and no prep. It is also self-marking in practice, which ordinary math worksheets are not - a wrong answer produces a culprit who cannot exist. Use it as a math activity, in math centers, or as 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\u003eMothers Day in May, alongside cards and gifts your class is already making\u003c\/li\u003e\n  \u003cli\u003eMultiplication and division fact practice that is not a timed test\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\u003eEnd of year review, when attention is thin and the work still has to happen\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 3rd grade and 4th grade.

Cases 1 to 7 stay within 100 ÷ 10. The Turkey Trot Trick and The Smudged Recipe Card give extra work on missing dividends, which ties division back to the times tables. In 4th grade, Cases 8 and 9 add the 11s and 12s, and the pack covers division facts all the way to 12 x 12. For 5th graders it's fact review, or intervention pages before long division. A single case also works for a small group or a bell ringer. You could leave one with sub plans for the days before the holiday, or send it home for homeschool practice.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMade for 3rd grade (3.OA.C.7) and 4th grade, where the division facts go up to 144 ÷ 12. 5th grade teachers can use it for fact review and intervention.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Teachers Love Mystery Detectives\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEvery Mystery Detective pack works the same way.
