Students answer \"times as many\" and \"times as much\" questions for 4.OA.A.1 and 4.OA.A.2, and the dinosaur museum theme suits any time of year. They're ready for math centers, morning work or homework in your multiplication and division unit. There's no prep, and each case comes with an answer key.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe first five cases stick to times table facts. The last five use 2-digit by 1-digit numbers, and cases 8 to 10 add a few \"how many more\" questions, where students need to subtract after they multiply. Each correct answer crosses one name off the suspect list, and the one left over is the villain.\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 15 word problems each, and an answer key for every case\u003c\/li\u003e\n  \u003cli\u003eThree kinds of question on every page: find the bigger amount, find the smaller amount, and \"how many times as many?\"\u003c\/li\u003e\n  \u003cli\u003eTimes table facts in cases 1 to 5.

Cases 8 to 10 also mix in \"how many more\" questions, and they make good review before a test. You can use the cases with small groups, on sub days, for test prep or in homeschool, and 5th grade teachers can use them for back to school review.\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 4th grade (4.OA.A.1 and 4.OA.A.2).
