Reginald Van Feisty, owner of the world-famous chocolate factory, Dutch Delight Chocolates, is excited about his brand-new recipe for chocolate. But, before he can manufacture even the first chocolate bar, the recipe is stolen! Have your students discover who stole Van Feisty's famous chocolate recipe and they'll not only be great detectives, they'll be masters of logical thinking. There are nine suspects, but which one is guilty? This mystery becomes a vehicle for teaching logical thinking. In solving the mystery, students will: differentiate between valid conclusions and invalid assumptions, use syllogisms to reach valid assumptions, recognize false premises, solve deductive matrix puzzles, and decode a secret message. Grades 5-8 The Great Chocolate Caper: A Mystery that Teaches Logic Skills is meant for the 5th-8th grader. I used it with my 5th grade son and 8th grade daughter who have both been doing logic puzzlers from early elementary age. They jumped into this with great excitement because the puzzlers were part of a mystery they had to help solve...Through a variety of logic exercises, your child whittles down the nine person suspect list until the culprit is discovered. He will solve matrix puzzles, determine valid vs. invalid assumptions, pinpoint false premises and valid conclusions, examine fingerprint clues and decode secret messages. ,Cindy West, 3/14/11 Mary Ann Carr began writing mysteries for kids to solve while teaching gifted students.
