{"product_id":"number-patterns-input-output-tables-mystery-detective","title":"Number Patterns, Input Output Tables | Mystery Detective Worksheets | Grades 2–4","description":"\u003cp\u003eThese number patterns worksheets give your 3rd grade class ten CSI Mini Mystery Detective cases set in a toy factory, all built around arithmetic patterns and 3.OA.D.9. Students extend patterns on conveyor belts, find the missing numbers on hundreds chart pieces, skip count through the times tables and work out the rule on input output tables. Use them in math centers, for morning work or as homework right through your patterns unit. They're no prep, and every case comes with an answer key.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFour of the ten cases are drawn pages, so students spend some cases filling in toy boxes on a moving belt and gaps in a machine table, and others working through written problems. Each answer crosses a suspect off the list, which means students check their own work as they go and the page marks itself. One case fits neatly into a 20 minute math block.\u003c\/p\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\u003e10 one-page cases with 20 answers each, and an answer key for every case\u003c\/li\u003e\n  \u003cli\u003e4 drawn pages: two conveyor belt pages, a hundreds chart puzzle page and an input output table page\u003c\/li\u003e\n  \u003cli\u003e6 pages of written problems: missing numbers, skip counting, doubling and halving, addition table patterns and mixed review\u003c\/li\u003e\n  \u003cli\u003eA reference page with a worked example for each kind of pattern\u003c\/li\u003e\n  \u003cli\u003eContents page, teacher instructions, a case log and a certificate\u003c\/li\u003e\n  \u003cli\u003e30 pages in black and white\u003c\/li\u003e\n\u003c\/ul\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 Runaway Robots\u003c\/strong\u003e - adding patterns on a conveyor belt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Squeaky Duck Swap\u003c\/strong\u003e - counting back along the belt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Wobbly Spinning Tops\u003c\/strong\u003e - missing numbers in a pattern\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Broken Building Blocks\u003c\/strong\u003e - skip counting the times tables\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Missing Puzzle Pieces\u003c\/strong\u003e - hundreds chart puzzle pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Double Dollhouse\u003c\/strong\u003e - doubling, tripling and halving patterns\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Bouncing Ball Blunder\u003c\/strong\u003e - patterns in the addition table\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Mixed-Up Machine\u003c\/strong\u003e - input output tables with a hidden rule\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Teddy Bear Heist\u003c\/strong\u003e - patterns and machines mixed together\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Drum Roll Disaster\u003c\/strong\u003e - a review of every pattern\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStart with cases 1 and 2 once your class has begun extending patterns, and save the hundreds chart and addition table cases for the lessons where you look for patterns in a chart. The input output tables in case 8 lead straight into the function tables of 4th grade, so it also makes a good stretch for a strong group. Cases 9 and 10 bring everything together, ready for review before a test. The pages work well for math centers, small groups, early finishers, sub days, test prep and homework.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMade for 3rd grade (3.OA.D.9).

Once your class has solved one case, they know what to do with the next one, in this pack or any other. Each case also stands on its own, which means you can choose the one that fits what you're teaching that day. Naming the villain gives every page a clear end point, and the answer key lets you check a page quickly.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWant more cases like these?\u003c\/strong\u003e\u003c\/p\u003e\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\u003cp\u003e\u003ca href=\"https:\/\/www.teacherspayteachers.com\/Sellers-Im-Following\/Add\/Kiwiland\"\u003ehttps:\/\/www.teacherspayteachers.com\/Sellers-Im-Following\/Add\/Kiwiland\u003c\/a\u003e\u003c\/p\u003e","brand":"Kiwiland Education","offers":[{"title":"Default Title","offer_id":62593080328562,"sku":"18009792","price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0909\/2848\/0626\/files\/number-patterns-worksheets-3rd-grade-math-input-output-tables-mystery.jpg?v=1792612400","url":"https:\/\/kiwilandeducation.com\/products\/number-patterns-input-output-tables-mystery-detective","provider":"Kiwiland Education","version":"1.0","type":"link"}
