No prep, print and go, with full answer keys, for math centers, morning work, early finishers, homework, test prep and sub plans any week of the year. Space bandits, drained robot oil and a machine that has malfunctioned carry the story, students borrow across zeros and match every answer to a clue, and a dropped digit simply never appears on the list, so they find it themselves at problem three rather than at marking time, all inside one CSI Mini Mystery Detective download that owes nothing to a holiday.\u003c\/p\u003e\n\n\u003cp\u003eFour digit subtraction asks for two borrows in the same problem, and this pack is where a student learns to trust their own answer. The clue list only carries the right ones, so they hunt down any digit they dropped themselves. The robots keep them at it until the borrowing is automatic, five robot math pages, Mystery Detective style, and not a pumpkin in sight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSpace Bandits - something has been taken from the ship\u003c\/li\u003e\n  \u003cli\u003eMissing Robot Oil - the supply has drained away overnight\u003c\/li\u003e\n  \u003cli\u003eRobot Malfunction - working out which machine failed\u003c\/li\u003e\n  \u003cli\u003eRobot Color - a paint job nobody owns up to\u003c\/li\u003e\n  \u003cli\u003eBad Robot - the last case, and the hardest to pin down\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Inside\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFive robot case files, sixteen subtraction problems on each\u003c\/li\u003e\n  \u003cli\u003eFour digit subtraction with regrouping throughout\u003c\/li\u003e\n  \u003cli\u003eAnswer keys for all five cases\u003c\/li\u003e\n  \u003cli\u003eSuspect and clue lists printed beside the problems\u003c\/li\u003e\n  \u003cli\u003eA teacher instruction page - print and go, nothing to cut\u003c\/li\u003e\n  \u003cli\u003eOne download, no prep, no laminating\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\u003eOne printed page holding one crime and the clue lists that solve it.

Use it for math centers, morning work, early finishers, homework, 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, and useful in 5th grade for students who still need subtraction firmed up before they meet decimals.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Teachers Love These Cases\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eA wrong answer matches no clue, so students find their own slips\u003c\/li\u003e\n  \u003cli\u003eRobots hold a class that has gone cold on plain worksheets\u003c\/li\u003e\n  \u003cli\u003eFive cases is a full week from one print run\u003c\/li\u003e\n  \u003cli\u003eWorks any month - nothing in it is tied to a season\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eLove this resource?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eFollow Kiwiland Education to discover more CSI Mini Mystery Detective cases, no-prep math activities, and detective-themed printables for elementary classrooms.\u003c\/p\u003e\n\n\u003cp\u003e\u003ca href=\"https:\/\/www.teacherspayteachers.com\/Sellers-Im-Following\/Add\/Kiwiland\" target=\"_blank\" rel=\"noopener\"\u003eFollow Kiwiland Education on TPT ↗\u003c\/a\u003e\u003c\/p\u003e","brand":"Kiwiland Education","offers":[{"title":"Default Title","offer_id":61955315794290,"sku":"5319817","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0909\/2848\/0626\/files\/4-digit-subtraction-with-regrouping-worksheets-3rd-4th-grade-5319817.jpg?v=1792460961","url":"https:\/\/kiwilandeducation.com\/products\/4-digit-subtraction-with-regrouping-mystery-detective-worksheets-grades-2-5-robot-theme","provider":"Kiwiland Education","version":"1.0","type":"link"}
