Grid Perplexors: Level B

Each Grid Perplexors puzzle starts with a story that challenges the reader to figure out who, what, where and when details using a list of clues. Each clue is a puzzle in itself, offering as much information about what's not true as what is. Through the process of elimination, plus handy pre-printed grids for organizing deductions, the reader will build their ability to think through complex problems and integrate into other disciplines. For Grades 4 and 5.
