Building Thinking Skills book 3 - Figural
These thinking skills books are among our favorites because of their tremendous scope. In this edition, they develop four basic analytical skills (similarities/differences, sequences, classification, and analogies) through figural problems only. In addition, there are problems dealing with deductive reasoning, map skills, Venn diagrams, mental manipulation of two-dimensional objects, and much more. Studies have shown that students using these books have significantly raised their national test scores in content and cognitive tests! What's more, these books are never dull!
