Nothing to prepare beyond pressing print: color and black and white versions, answer keys for every page. The case is The Missing Roller Skates - in the bag last night, gone this morning - and your students have until the rink opens to solve the mystery. Answers pick letters off a map and settle an odd-or-even trail, ruling out a suspect each time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Case: The Missing Roller Skates\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYour best friend has invited you to the rink and you have not been skating in years.
