Logic I: Tools for Thinking is used as an introductory or second-year textbook for students in grades 8 or 9 and above (and some 7th graders), in homeschool, co-op, and Christian school settings. Logic I: Tools for Thinking covers a wide range of topics in both formal and informal logic accurately and engagingly. Humorous and serious examples are drawn from a wide range of subject areas: religion, history, politics, literature, science, taxes, and more. If you're looking for in-depth coverage at a sensible pace—with no logic background required—and you want a thoroughly Christian perspective on logic, then Logic I: Tools for Thinking is for you.
Scope of Logic I: Tools for Thinking
Logic I begins with vital foundational topics: thinking and reasoning, what logic is, language and how it relates to logic.
The course then moves on to statements and logical operators, along with various tools to use on them. Topics include negation, contradiction, conjunction, disjunction, equivalence, and implication.
On this foundation one of the most useful modern formal (or deductive) logic systems, the sentential calculus, is developed in detail. Formal logic has broad application in such areas as mathematics and computer programming.
The book closes with a substantial section devoted to informal (or inductive) logic. Informal logic encompasses the types of arguments students encounter on a daily basis.
This combination of formal and informal logic topics makes Logic I: Tools for Thinking unusual in its breadth and usefulness. If you're looking for a substantial, year-long course which will strengthen your child's thinking skills (and stimulate yours too!), this course is for you.
What do I order?
If you will be schooling more than one child, order one student book for each child you are teaching, plus one student book and one teacher's manual for yourself.
If you will be schooling just one child and do not mind sharing the student book, then just order one teacher's manual and one student book, total. If you will be schooling just one child but want your own student book, then order one teacher's manual and two student books. (Note that the student book is not a workbook; all exercises are done on separate paper. So sharing the student book is possible even if you, too, wish to do all the exercises.)
Will I need a new book each year for each student?
No, that won't be necessary because of the durable construction (heavy-duty laminated cover with plastic spiral binding, not comb binding). Schools generally get several years' use out of one student book.
