No prep, print and go, full answer keys, for morning work, math centers, early finishers, homework and sub plans through December. December is a good month for subtraction with regrouping practice, and this pack gives 2nd grade and 3rd grade students a week of it inside a school Christmas story. It works as Christmas math activities for math centers, morning work or the class party week, and a CSI Mini Mystery Detective marks itself.\u003c\/p\u003e\n\n\u003cp\u003eBorrowing fits the week of the class party perfectly when there is a reason to care, and an unsigned box of chocolates on the desk is that reason. The pages mark themselves as students cross the suspects off. It is math practice and a Mystery Detective case in one.\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\u003eClass Secret Santa\u003c\/strong\u003e - a gift with no label\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChristmas Chocolates\u003c\/strong\u003e - chocolates on the desk, unsigned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChristmas Carols\u003c\/strong\u003e - singing from the music room\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChristmas Presents\u003c\/strong\u003e - who unwraps theirs first\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChristmas Good Deeds\u003c\/strong\u003e - kindness and nobody owning up\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 Christmas cases, each a page of 3 digit subtraction with regrouping\u003c\/li\u003e\n  \u003cli\u003eSixteen questions per case, laid out in columns ready to borrow\u003c\/li\u003e\n  \u003cli\u003eClue lists down the side of every page, so one answer removes one clue\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: no cutting, no laminating, nothing to 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 one page carrying a crime, a short list of clues and the questions that eliminate them.
