Primarily Logic [PDF ebook] 
Grades 2-4

It’s never too early to start building thinking skills-skills that will spill over into other areas of the curriculum and into real life. Primarily Logic consists of a series of units designed to introduce logical thinking to young students. It is an excellent, easy-to-use starting point for teaching well-established forms of logical thinking. Each skill is introduced with examples, and then worksheets give students an opportunity to practice the skill. Group lessons and worksheets provide practice in: finding relationships, analogies, thinking logically using "all" and "none" statements, syllogisms, and deductive reasoning using logic puzzles. Logical thinking is both enjoyable and challenging for students as they build a sound foundation for further instruction in critical thinking. Suggestions for related activities are included in the Instructions for Teachers section.For easier logic activities for younger students, try Lollipop Logic.Grades 2-4
