It's 3.NBT.A.3 practice that starts with multiply by tens facts and moves on to multiplication word problems and two-step problems. Use the cases in math centers, as morning work or for homework while you teach multiplication. They're no prep, and you get an answer key with every case.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eHalf of the cases are drawn pages. Students count candy boxes, read prices off a prize counter, fill in a times grid, jump along number lines and finish order forms for a birthday cake. The other half are written problems. Every answer crosses one suspect off, and the one left at the end is the villain. Students check their own work as they go, and you have very little grading to do.\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 problems on each, 200 problems in all\u003c\/li\u003e\n  \u003cli\u003eAn answer key for every case\u003c\/li\u003e\n  \u003cli\u003e5 drawn pages and 5 pages of written problems\u003c\/li\u003e\n  \u003cli\u003eA reference page with examples: tens, using a fact you know, the times grid, how many more, two-step problems and number lines\u003c\/li\u003e\n  \u003cli\u003eContents, teacher instructions, a case log for students and a Head Candy Inspector certificate\u003c\/li\u003e\n  \u003cli\u003e30 pages.

Students see the tens as boxes of chocolate, ticket prices, grid columns and jumps on a number line before they work with the numbers on their own. Case 5 asks how many more, and Case 6 adds a second step. Cases 7 and 8 put the skill into order forms and word problems. The last two mix everything, including turnaround facts, repeated addition and parentheses, and they're a good fit for test prep. You can also give a single case to a small group, leave a few in your sub plans or use them for homeschool practice.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWritten for 3rd grade (3.NBT.A.3). 4th grade classes can use it as a warm-up before multiplying bigger numbers in 4.NBT.B.5.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Teachers Love Mystery Detectives\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEvery Mystery Detective pack works the same way.
