No prep, print and go, full answer keys: math centers, morning work, early finishers, homework and sub plans for the short week around the holiday. Lincoln's hat goes missing, a speech loses its pages and a class election count refuses to add up, students add down the page and every correct total crosses off a suspect, so a carrying slip matches no clue and gets fixed on the spot, five CSI Mini Mystery Detective cases that also give the wall something to show in February.\u003c\/p\u003e\n\n\u003cp\u003eFebruary is a short month with a holiday in the middle, and two digit addition is exactly the skill worth polishing after a long weekend. These cases make the revision feel like a game, and the presidents give you something to pin up in a month that usually has nothing. Five pages of Presidents Day math, one Mystery Detective to name before the balloons go missing.\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 files, 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, 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 lists that solve it.

It works as homework across the holiday week, as a February center, and as something to leave for a substitute. Use it in math centers, for morning work, with early finishers, for homework, in sub plans and in homeschool lessons, with a whole class, a small group or one student on their own.\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, and useful in 4th grade for students who still lose the carry.
