Print and go with full answer keys: no prep math activities for math centers, early finishers, morning work, homework and sub plans. Subtraction with regrouping is the skill 2nd grade and 3rd grade students need the most practice at, and these school mysteries give it to them without a plain worksheet in sight. Use the pack for math centers, morning work or early finishers, and a CSI Mini Mystery Detective marks itself.\u003c\/p\u003e\n\n\u003cp\u003eBorrowing is the point in the subtraction unit where repetition pays off most, and a student in trouble whose name nobody knows is what gets five pages of it done with a smile. Students cross a suspect off with every answer, checking their own borrowing as they go, and the pages mark themselves. One CSI Mini Mystery Detective math case fits a morning work slot.\u003c\/p\u003e\n\u003cp\u003eOne case follows a student picking up trash around the playground, and another is about an apple missing from a lunch box. Students subtract, then cross off the clue that matches. When they borrow correctly, the clue lists narrow down to a single answer.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Apple\u003c\/strong\u003e - an apple taken from a lunch box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaught Being Good\u003c\/strong\u003e - who has been doing good deeds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinding Trash\u003c\/strong\u003e - a student cleaning up the playground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIn Trouble\u003c\/strong\u003e - which student got in trouble\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Surprise Present\u003c\/strong\u003e - an unsigned gift for the teacher\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFive cases of 2 digit subtraction with regrouping\u003c\/li\u003e\n  \u003cli\u003eA borrow in every problem\u003c\/li\u003e\n  \u003cli\u003eBlack and white copies of all five\u003c\/li\u003e\n  \u003cli\u003eAn answer key for every case\u003c\/li\u003e\n  \u003cli\u003eTeacher instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat Is a CSI Mini Mystery Detective?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA CSI Mini Mystery Detective is a single page: a crime, a set of problems and short clue lists beside them.
