{"product_id":"addition-subtraction-multiplication-csi-mystery-presidents-day","title":"Presidents Day CSI Mystery Worksheets | Grades 2–5 | The Missing Hat","description":"\u003cp\u003eFebruary Presidents Day CSI math worksheets that play out as a CSI Mystery Detective case on three-digit addition and multiplication facts, with a missing stovepipe hat and a speech due in an hour. Aimed at 3rd grade, 4th grade and 5th grade, it is a multiplication mystery for the week around Lincoln's birthday and a handy snow day math option too. Both color and black-and-white pages are included and nothing needs cutting. Students follow a trail of stars where an odd or even total settles the clue, decode addition answers through a letter key, and circle letters on a multiplication grid to unscramble the final name, sending one suspect home with every right answer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: Help!

The speech is in an hour, and somebody in this house has taken it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAddition along a trail of stars where an odd or even total settles the clue\u003c\/li\u003e\n  \u003cli\u003eThree-digit addition decoded through a letter key to give a shoe size\u003c\/li\u003e\n  \u003cli\u003eChecking worked answers for errors and tallying which are correct\u003c\/li\u003e\n  \u003cli\u003eMultiplication used to color the correct circle and arrow forward\u003c\/li\u003e\n  \u003cli\u003eCircling letters on a grid using multiplication answers, then unscrambling them\u003c\/li\u003e\n  \u003cli\u003eFull color and black-and-white versions of every page\u003c\/li\u003e\n  \u003cli\u003eAnswer keys for the whole case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mystery Detective Case?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eA CSI Mystery Detective case is a printable investigation your class solves with math. It runs like a math escape room - no locks, no app, no prep - except that instead of opening a box, every correct answer rules one suspect out of the line-up until a single name is left. That is what separates detective activities from ordinary math worksheets: the arithmetic has to be right or the case will not close, so students check their own work. It is a math activity that carries a whole lesson, and it works just as well in math centers or as a sub plan.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePresidents Day in February, alongside your history work\u003c\/li\u003e\n  \u003cli\u003eThe days around a holiday, when you still want real math done\u003c\/li\u003e\n  \u003cli\u003eMath centers, early finishers and independent work\u003c\/li\u003e\n  \u003cli\u003eEmergency sub plans that run themselves\u003c\/li\u003e\n  \u003cli\u003eEnd of year review, when attention is thin and the work still has to happen\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eBuilt for 3rd grade, 4th grade and 5th grade.
