Print and go, no prep, full answer keys and a black and white set, for math centers, morning work, early finishers, homework, sub plans and math review any week of the year. The cases are everyday school stories, so this works in any month, and it gives 3rd grade and 4th grade students the 2 digit by 1 digit multiplication practice they need once the times tables are known. Teachers use it for multiplication review before a test or as a math center that runs on its own, one CSI Mini Mystery Detective case a day.\u003c\/p\u003e\n\n\u003cp\u003eThis is the step where students meet carrying inside multiplication for the first time, and plenty of repetitions is what makes it stick. The case gives them a reason to enjoy twenty, and the lineup makes every page self-marking. It is the sister pack to the times tables 2 by 1 set, with different cases and the same Mystery Detective math.\u003c\/p\u003e\n\u003cp\u003eThis is often the first time students carry in multiplication, and each case gives them a full page of problems to practice it. The answers match numbers in the clue lists, and students cross each one off as they find it. A missed carry leads to a number that isn't there, which tells them to look again.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Bike\u003c\/strong\u003e - a bike stolen from a friend\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeacher Appreciation Mystery Gift\u003c\/strong\u003e - a gift with no name on it\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Vacation\u003c\/strong\u003e - which student is going where\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Teachers Lunch\u003c\/strong\u003e - the teacher's missing lunch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStudent Prize\u003c\/strong\u003e - a student doing good deeds\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFive case pages in color\u003c\/li\u003e\n  \u003cli\u003eAll five cases in black and white\u003c\/li\u003e\n  \u003cli\u003eAnswer keys\u003c\/li\u003e\n  \u003cli\u003e2 digit by 1 digit multiplication throughout\u003c\/li\u003e\n  \u003cli\u003eA teacher instruction page\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProblems go on the left of the page, and on the right are lists of names, places and times, each with a number.
