Print and go, no prep, full answer keys, for March math centers, morning work, early finishers, homework and sub plans. A pot of gold found first, Irish songs in the hall and the leprechaun's gold gone from the pot carry the week, the right sum clears a suspect and the wrong one clears nobody, so every CSI Mini Mystery Detective page is real practice that marks itself.\u003c\/p\u003e\n\n\u003cp\u003eFive separate CSI Mini Mystery Detective math cases give you five days of March practice without repeating a page, and a class adds its way eagerly to the culprit.

Each suspect carries a number, each solved question matches one of them, and that suspect is crossed off until a single name remains. Because a wrong sum eliminates the wrong person, these detective activities make students check their work in a way math worksheets cannot. One case fills a class period.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eMarch, when three digit carrying was taught back in the fall and half the class has quietly stopped doing it properly.
