No prep, print and go, full answer keys and a black and white set, for math centers, morning work, early finishers, homework and sub plans in the February holiday week. Lincoln's hat has gone, the speech has lost its pages and the class vote will not add up, and every correct total crosses a suspect off until one is left; a missed carry matches no clue, so it gets caught at the desk, which is what makes a CSI Mini Mystery Detective the sum practice a class will actually finish the week before a long weekend.\u003c\/p\u003e\n\n\u003cp\u003eThe middle of February is a short run of days between two breaks, and three digit carrying is the skill worth keeping sharp through it. These cases give the practice a reason to exist without spending a lesson on the presidents themselves. Five days of math, one Mystery Detective culprit by Friday, and the hat back on Lincoln's head.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePresident Lincolns Hat - the hat has gone missing\u003c\/li\u003e\n  \u003cli\u003eThe Missing Speech - somebody has taken the pages\u003c\/li\u003e\n  \u003cli\u003ePresident Costume - working out who wore what\u003c\/li\u003e\n  \u003cli\u003eVoting Class President - a count that does not add up\u003c\/li\u003e\n  \u003cli\u003eMissing Balloons - the last case, on election day\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\u003eThree 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.
