Built for 2nd grade and 3rd grade, it turns a plain addition and subtraction mystery into a hunt for whatever dug to the bottom of the backpack, because the culprit left just enough behind to be identified. Every page prints in color or black and white, and answer keys are included. Students complete number sequences to reveal the next part of the description, work linked questions down to one final number and use subtraction clues, shortening the line-up with every right answer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: Jungle Juice Fever\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYour students wake up in the jungle after a long night, starving. They climb out of the sleeping bag, reach for the backpack and dig right down to the bottom, because the good stuff was buried where nothing could get at it. It is not there.

Students solve, each correct answer strikes one name off the suspect list, and the case closes on the last one standing. There is nothing to unlock, download or prepare - it is a math escape room made of paper. Detective activities police themselves in a way ordinary math worksheets cannot: an error leaves a culprit nobody can arrest, so the class goes back over it. A math activity that carries a lesson, a center rotation, or 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\u003eAddition and subtraction review before or after a unit test\u003c\/li\u003e\n  \u003cli\u003eBack-to-school weeks and end of year review\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\u003eA jungle, rainforest or animals topic week, alongside reading or science work\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.
