{"product_id":"2-digit-addition-regrouping-mystery-detective-worksheets","title":"2-Digit Addition with Regrouping | Mystery Detective Worksheets | Grades 1–4 | Printable Detective Pack","description":"\u003cp\u003e2 digit addition with regrouping math activities for 1st grade and 2nd grade: five math cases, each a Mystery Detective page, carrying from the ones into the tens. Print and go with full answer keys: no prep math worksheets for morning work, math centers, early finishers, homework and sub plans. Two digit addition with regrouping for 1st grade and 2nd grade, set around school so it works in any month, and short enough for a young class to finish. It suits math centers, morning work and early finishers, and it prints and goes as five CSI Mini Mystery Detective cases.\u003c\/p\u003e\n\n\u003cp\u003eCarrying is the step a young class needs the most practice at, and a teacher who is nowhere in the school is what keeps them happily at it for five pages. Students match each total to a suspect and cross that name off, which means they are checking their own carrying as they go. One case fills a morning work slot, and every CSI Mini Mystery Detective math sheet marks itself.\u003c\/p\u003e\n\u003cp\u003eStudents add each pair of numbers, carrying from the ones to the tens, then look for the total in the clue lists. A neighbor's missing phone, a teacher who hasn't turned up and a mystery reward are three of the cases. A child who finishes with one clue in each list has got the carrying right.\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 Phone\u003c\/strong\u003e - a neighbor's phone has been taken\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Teachers Lunch\u003c\/strong\u003e - the teacher's lunch is gone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Teacher\u003c\/strong\u003e - where a teacher has gone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWho Got in Trouble\u003c\/strong\u003e - which student was in trouble\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Mystery Reward\u003c\/strong\u003e - who did the great work\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 addition with regrouping\u003c\/li\u003e\n  \u003cli\u003eClue lists down the side of each page\u003c\/li\u003e\n  \u003cli\u003eBlack and white copies\u003c\/li\u003e\n  \u003cli\u003eAnswer keys\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\u003eEach case is one page with a short story, some addition problems and clue lists for who, where and when.
