The ten printable cases have a pumpkin festival theme. Put these Halloween math activities in your October math centers, or use them for morning work, homework and early finishers. Answer keys are included.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eUse this pack in October, toward the end of your place value unit. Students round to the nearest 10 up to the nearest 100,000, find the value of an underlined digit, and turn expanded form into standard form. They match each answer to a suspect's badge and cross the name off, and the pages are self-checking. The grade 3 cases come first, and the grade 4 cases build from there.\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\u003eTen one-page detective cases on place value and rounding, each with an answer key\u003c\/li\u003e\n  \u003cli\u003eFour 3rd grade cases: rounding to the nearest 10 and 100, the value of a digit, and expanded form\u003c\/li\u003e\n  \u003cli\u003eSix 4th grade cases with 5- and 6-digit numbers, finishing with a mixed review case\u003c\/li\u003e\n  \u003cli\u003eA reference page with a worked example for every skill\u003c\/li\u003e\n  \u003cli\u003eA contents page, teacher instructions, a detective case log and a certificate of achievement\u003c\/li\u003e\n  \u003cli\u003e30 black and white pages, ready to print\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 Giant Pumpkin Swap\u003c\/strong\u003e - round pumpkin weights to the nearest 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Cauldron Candy Raid\u003c\/strong\u003e - round candy counts to the nearest 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Haunted Hayride\u003c\/strong\u003e - value of the underlined digit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Costume Parade Mix-Up\u003c\/strong\u003e - expanded form to standard form\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Bat Cave Blackout\u003c\/strong\u003e - digit values in 6-digit numbers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Tangled Web\u003c\/strong\u003e - expanded form with the parts mixed up\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Snuffed-Out Candles\u003c\/strong\u003e - find the missing expanded form part\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Broomstick Race\u003c\/strong\u003e - round to the nearest thousand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Fallen Moon\u003c\/strong\u003e - round to 10,000 and 100,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe Lost Halloween\u003c\/strong\u003e - every place value skill, mixed\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\u003eThe cases start with rounding to the nearest ten and hundred, then the value of each digit, expanded form, and the same ideas with bigger numbers. A 3rd grade class can work through the first four cases and stop there, while a 4th grade class can use them as a warm-up before the larger numbers. The final mixed case is a good end of unit check, and you can hand out one case a day across Halloween week. Guided math groups, bell ringers, test prep, sub days, homeschool and fall review are other good fits.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCases 1-4 are written for 3rd grade, with numbers up to 9,999.
