Logic Liftoff, Grades 4-6
Blast Off with Logicis a series of three books that build upon one another at increasing levels of difficulty.Logic Countdown, written for grades 3–4, introduces relationships, analogies, sequencing, "all" and "no" statements, syllogisms, if-then statements, deduction, and making inferences.Logic Liftofffor grades 4–6 reviews and expands all of these topics, continues into deeper logical reasoning, and introduces logical notation.Orbiting with Logicfor grades 5–7 builds on the previous two books, expands logical notation, and adds logic diagrams and logical fallacies. While it is possible to use any one of the books alone, they really work best as a sort of continuous course . . . Most of us parents will find many of the lessons new and challenging, so we should tackle them right along with our children to improve our own thinking skills. --Cathy Duffy, Cathy Duffy Reviews - January 1, 2009
