Your students pull on their detective coats, sharpen their pencils, and report to the crime scene — the only way to identify the culprit is to follow the math.\u003c\/p\u003e\n\u003cp\u003eThe case opens with a coded number puzzle. Students crack it to line up their first set of suspects, then dig into the evidence: breaking numbers into hundreds, tens, and ones, ordering three-digit numbers in a police lineup, and sorting the odd suspects from the even ones. Every clue clears a few more numbers from the board.\u003c\/p\u003e\n\u003cp\u003eThen the witnesses weigh in. Students work 10-more and 10-less, 1-more and 1-less clues across hundred-chart pieces to corner the final suspects — but the truth is still hiding. In the last interrogation, a completed hundreds chart forces the guilty number into the open at last.\u003c\/p\u003e\n\u003cp\u003eHand your students the evidence, point them at the suspects, and let them prove they can crack the case. The math is the only thing standing between them and the truth.\u003c\/p\u003e\n\u003ch3\u003eSkills Covered\u003c\/h3\u003e\n\u003cp\u003eStudents will practice:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePlace value with hundreds, tens, and ones\u003c\/li\u003e\n  \u003cli\u003eOrdering numbers to 1,000\u003c\/li\u003e\n  \u003cli\u003eIdentifying odd and even numbers\u003c\/li\u003e\n  \u003cli\u003e10 more, 10 less, 1 more, and 1 less\u003c\/li\u003e\n  \u003cli\u003eCodebreaking with a number puzzle\u003c\/li\u003e\n  \u003cli\u003eCompleting a hundreds chart\u003c\/li\u003e\n  \u003cli\u003eUsing answers to eliminate suspects\u003c\/li\u003e\n  \u003cli\u003eLogic, reasoning, and problem solving\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCSI-style math mystery activity\u003c\/li\u003e\n  \u003cli\u003ePlace value and 3-digit number clue pages\u003c\/li\u003e\n  \u003cli\u003eNumber ordering and odd\/even puzzles\u003c\/li\u003e\n  \u003cli\u003e10 more \/ 10 less and hundreds-chart puzzles\u003c\/li\u003e\n  \u003cli\u003eSuspect elimination activity\u003c\/li\u003e\n  \u003cli\u003eAnswer key\u003c\/li\u003e\n  \u003cli\u003ePrint-and-go PDF format\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBest Used For\u003c\/h3\u003e\n\u003cp\u003eThis printable CSI Math Mystery works well for:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBack-to-school math review (and all-year use)\u003c\/li\u003e\n  \u003cli\u003eMath centers and early finishers\u003c\/li\u003e\n  \u003cli\u003eSubstitute teacher plans\u003c\/li\u003e\n  \u003cli\u003eSmall groups and independent work\u003c\/li\u003e\n  \u003cli\u003eHomeschool math\u003c\/li\u003e\n  \u003cli\u003eEnd-of-unit review\u003c\/li\u003e\n  \u003cli\u003ePlace value practice and reinforcement\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kiwiland Education","offers":[{"title":"Default Title","offer_id":61980801270130,"sku":"3178592","price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0909\/2848\/0626\/files\/place-value-csi-math-mystery-grades-2-6-cover.jpg?v=1782475709","url":"https:\/\/kiwilandeducation.com\/products\/place-value-csi-math-mystery-worksheets-grades-2-6-the-three-digit-suspect","provider":"Kiwiland Education","version":"1.0","type":"link"}
