Three cases round to the nearest 10 and three to the nearest 100, so the pack covers the whole standard, and a number rounded the wrong way matches no clue. Print and go with full answer keys: no prep math centers, morning work, early finishers, homework and sub plans, six Mystery Detective cases of math in one download.\u003c\/p\u003e\n\n\u003cp\u003eRounding is taught in a fortnight and then quietly forgotten, and the last weeks of December are exactly when it needs a run, because a stolen pile of presents and a gingerbread thief will get a third grade class through six pages of it. One case a day covers the fortnight before the break, and the answer keys keep the marking short. Every CSI Mini Mystery Detective math page checks itself.\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\u003eMissing Xmas Presents\u003c\/strong\u003e - the school lot has gone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWho Ate The Gingerbread\u003c\/strong\u003e - a classmate got there first\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecret Santa\u003c\/strong\u003e - a gift and no name on it\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeachers Xmas Present\u003c\/strong\u003e - a parcel nobody can explain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChristmas Fruitcake\u003c\/strong\u003e - somebody baked for everyone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWho Ate The Xmas Cookie\u003c\/strong\u003e - it happened again\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\u003eSix Christmas cases, three on the nearest 10 and three on the nearest 100\u003c\/li\u003e\n  \u003cli\u003eA clue list beside the questions, so one answer removes one name\u003c\/li\u003e\n  \u003cli\u003eA red-ink answer key for all six cases\u003c\/li\u003e\n  \u003cli\u003eSix separate Christmas stories, so no two pages read the same\u003c\/li\u003e\n  \u003cli\u003eSized for one class period a 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 a printable case: one crime, one short clue list, and the questions that rule the clues out. Each clue carries a number, the rounding produces those numbers, and a match crosses that clue off until one name is left. Round to the wrong place and nothing matches, which is what makes the page mark itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDecember is where this one belongs, in the fortnight before the break when a plain page of numbers will not hold a class. It also does a real job in the new year, because rounding is among the first things to go rusty over a holiday. The six cases split neatly into two sets of three, so you can hand out the nearest 10 group first and keep the nearest 100 group for the following week.\u003c\/p\u003e\n\n\u003cp\u003eUse it for morning work, math centers, early finishers, homework, test prep, 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 3rd grade and 4th grade.
