What do these workbooks contain?
There are three sections in each workbook - verbal, analytical, and pictorial. The verbal reasoning sections in workbooks 0-2 get you started quickly in critical reading/thinking and logical reasoning through examples and exercises in finding the truth of statements, word and sentence analogies, inferences, and more.
The verbal reasoning section in workbooks 3-5 introduces concepts of logic such as conditional statements, categorical statements, causal statements, and inferencing (deduction). You become a critical reader by keeping a watchful eye on certain keywords that have a bearing on the logic in the statements. You become a critical thinker by knowing how to infer (deduce) the unstated.
The verbal reasoning section in the Primer book is a prerequisite for workbooks 6-10. It introduces argument structure, different types of arguments, deductive and inductive reasoning, and finding flaws in reasoning. The content in this book will help you be a critical reader and thinker. This book lays out the essential foundation for workbooks 6, 7, 8, 9, and 10.
Verbal reasoning in workbooks 6-10 includes different types of exercises involving various types of arguments with the goal of making you a critical reader, writer, thinker, and speaker.
The analytic reasoning section in workbooks 0-2 help you develop the ability to solve problems that require thinking about possibilities, positioning, and grouping. Workbooks 3-5 introduce list processing, scheduling, sequencing, correlation, Venn diagrams, graph logic, and more.
Analytical reasoning content in workbooks 6-10 includes more complex positioning and grouping problems. Sudoku exercises are a great way to tune your analytical mind and are included in the analytical reasoning sections in all the 10 workbooks.
The pictorial reasoning section develops your visual reasoning skills by looking at pictures and understanding their contents and relation to other pictures. In workbooks 0-2, exercises to spot the difference between pictures, to find the next picture from a sequence of pictures, and to spot the odd picture from a set of pictures are introduced. In workbooks 3-5, pictorial analogy and pattern matching are introduced. In workbooks 6-10, advanced pictorial reasoning exercises involving pattern perception, paper folding and cutting, figure formation, figure matrix, figure analogy, and rule detection are introduced.
Is any math required?
These books are not about math. They are about developing your thinking skills in the verbal, analytical, and pictorial reasoning areas. Most of the material does not involve math at all. Basic addition, subtraction, multiplication, and division are all that is necessary in some sections of these books.
