Orbiting with Logic (Blast Off with Logic)
A series of three reproducible books designed to develop logic skills in a sequential, developmental fashion. The three books increase in levels of difficulty. The first introduces relationships, analogies, sequencing, "all" and "no" statements, syllogisms, if-then statements, deduction, and inferring. The next progresses in these skills at a deeper level, includes logical reasoning, and introduces logical notation. The final book builds on the foundation of the first two books, and adds logic diagrams and logical fallacies. You should really start your student(s) at the beginning of this series to get the most benefit from it, but they can progress through it as able.
