Blast Off With Logic is 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 Liftoff for grades 4-6 reviews and expands all of these topics, continues into deeper logical reasoning, and introduces logical notation. Orbiting with Logic for 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
About the Author
Bonnie Lou Risby grew up in the Illinois woodlands atop the limestone bluffs across the Mississippi River from St. Louis. These woods were her playground where she and her siblings camped out, played detective, and enjoyed the beauty of the outdoors in every season. After attending college at Southern Illinois University Edwardsville, she taught school in Columbia, IL, for 13 years. She has taught elementary school, middle school, and high school, concentrating on the subjects of French, English, and gifted education. When Risby helped write the grant to establish Columbia's Gifted Program in the early 1970s, there were few materials readily available that fit well with a one-period per week pullout program.
After the birth of her son, Risby retired from teaching and joined a family and marriage counseling practice for 12 years, continuing to write and create logic books in her spare moments. Retired from her therapy practice, she now works in a family business with her husband and son in Ballwin, MO. Risby has continued to write classroom books, chapter books, magazine articles, and books for young adults.
Besides writing, Risby loves taking float trips down Ozark streams, biking, long walks with her dog, gardening, family history, and travel.
