No prep, print and go, full answer keys and a black and white set: math centers, morning work, early finishers, homework and sub plans for the first week back after Christmas. A party popper goes off early, a gift has no giver and the countdown does not add up, and each correct total crosses a suspect off until one is left, so a carrying slip matches no clue and gets fixed on the page, five CSI Mini Mystery Detective cases that settle a class back into the year without you at the front.\u003c\/p\u003e\n\n\u003cp\u003eThe week a class comes back is the perfect week for a hunt, and a party popper set off early holds everybody on the second of January. Two digit addition with regrouping is the right thing to revisit, and wrapping it in a case buys the attention. It is New Year math with a Mystery Detective to catch, and every page is self-marking.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eParty Popper - who set it off early\u003c\/li\u003e\n  \u003cli\u003eNew Year Gift - the gift nobody owns up to\u003c\/li\u003e\n  \u003cli\u003eAuld Lang Syne - working out who sang what\u003c\/li\u003e\n  \u003cli\u003eNew Year Countdown - a count that does not add up\u003c\/li\u003e\n  \u003cli\u003eNew Year Party - the last case of the night\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFive color case pages, sixteen addition problems on each\u003c\/li\u003e\n  \u003cli\u003eThe same five cases again in black and white\u003c\/li\u003e\n  \u003cli\u003eAnswer keys for all five cases\u003c\/li\u003e\n  \u003cli\u003eA color in page for early finishers\u003c\/li\u003e\n  \u003cli\u003eA teacher instruction page, print and go with nothing to prepare\u003c\/li\u003e\n  \u003cli\u003eTwo digit addition with regrouping throughout\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\u003eOne printed page holding one crime and the clue list that solves it.

It works as homework over the break, as a January center, and as a set to leave for a substitute. Use it for math centers, morning work, early finishers, homework, sub plans and homeschool lessons, with a whole class, a small group or one student.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eWritten for 2nd grade and 3rd grade.
