Why should spellers and geography buffs have all the fun? Why not a “thinking bee?” Although this series was designed to be used in contests, the exercises can be done individually. Each book is divided into six sections that focus on different types of higher-level thinking skills. Includes detailed instructions, answer keys, and certificate of completion.

Covers: hypothesizing, choosing which one does not belong, making comparisons, trivia, math and logic, and language skills.
