No prep, full answer keys, print and go: math centers, morning work, early finishers, homework and sub plans for December, January and February. Hot chocolate, a snowball fight and a snow angel with no footprints carry the theme, each total crosses a suspect off the lineup until one name is left, and the carrying underneath is the practice a young class needs, one CSI Mini Mystery Detective page at a time.\u003c\/p\u003e\n\n\u003cp\u003eJanuary is when a young class needs a reason to sit and add, and a snow angel nobody will own up to is a better reason than a worksheet. Each total a child finds rules a suspect out, one CSI Mini Mystery Detective math case fits a morning work slot, and the answer keys are behind every page so the marking is done before recess.\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\u003eHot Chocolate\u003c\/strong\u003e - who made the teacher a hot chocolate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWinter Scarf\u003c\/strong\u003e - left behind in the classroom\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToboggan\u003c\/strong\u003e - everybody wants the next run\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSnowball Fight\u003c\/strong\u003e - who threw the very first one\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSnow Angel\u003c\/strong\u003e - a snow angel and no footprints\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 case files, each with a crime sheet and its own lineup of suspects\u003c\/li\u003e\n  \u003cli\u003eTwo digit addition with regrouping, with carrying on most problems\u003c\/li\u003e\n  \u003cli\u003eSums in columns with room to write the carried ten\u003c\/li\u003e\n  \u003cli\u003eEach answer matches one suspect and no other, so the page checks itself\u003c\/li\u003e\n  \u003cli\u003eA full answer key for every case\u003c\/li\u003e\n  \u003cli\u003ePrint and go: no cutting, no laminating, nothing to prepare\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, one crime and one class period. Each suspect in the lineup is tagged with a number, the questions produce those numbers, and a correct answer knocks a suspect out until the last one standing is the culprit. Nothing needs cutting, laminating or charging, which is why these detective activities get handed out on days that would otherwise call for math worksheets. It works as a lesson, in math centers, or left for a substitute.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDecember through February, and especially the day a snow day has wrecked your plan and half the class is somewhere else. Carrying needs regular short practice to stay put, and five short cases give you five days of it without repeating a page. Because the wrong total crosses off the wrong suspect, a child who forgets the carry finds out right there instead of at the end of the week.\u003c\/p\u003e\n\n\u003cp\u003eUse it for test prep, homework, math centers, morning work, early finishers, sub plans and homeschool lessons, with a whole class, a small group or one child.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eWritten for 1st grade and 2nd grade, where two digit regrouping sits in the standards.
