Print and go with full answer keys: no prep math activities for morning work, math centers, early finishers, homework and sub plans. Short pages of 2 digit addition without regrouping for 1st grade and 2nd grade, set around school, that a six year old can finish and feel good about. They suit math centers, morning work and early finishers in the first half of the year, with a CSI Mini Mystery Detective story on every page.\u003c\/p\u003e\n\n\u003cp\u003eThe first half of first grade is where addition without carrying gets its practice, and a missing toy to find is what makes the practice worth doing for a six year old. Every total takes a clue off the list, so they finish the page to learn who did it, and one case fits a morning work slot. Each CSI Mini Mystery Detective math page is self-marking, with an answer key included.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Toy\u003c\/strong\u003e - a classmate's toy has gone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMystery Present\u003c\/strong\u003e - a gift with no name on it\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Fruit\u003c\/strong\u003e - someone took the lunchbox fruit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Student\u003c\/strong\u003e - one child is absent, nobody knows who\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGotcha\u003c\/strong\u003e - a student caught doing the right thing\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFive case files, each one page of 2 digit addition with no regrouping\u003c\/li\u003e\n  \u003cli\u003eSixteen sums on every case, with every total under 100\u003c\/li\u003e\n  \u003cli\u003eFour clue lists on each page, so the class names the who, the where, the when and the what\u003c\/li\u003e\n  \u003cli\u003eA black and white copy of all five cases for everyday printing\u003c\/li\u003e\n  \u003cli\u003eAn answer key for every case\u003c\/li\u003e\n  \u003cli\u003ePrint and go: nothing to cut, laminate or set up\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA CSI Mini Mystery Detective is a single printed page with a crime on it and four lists of clues running down the side.
