The student text is available for free online, or it can be purchased as a physical book, at this web address: http://mises.org/resources/5706/Lessons- for-the-Young-Economist . The student text was designed with junior high students in mind, but it is applicable for younger, precocious students, and also even for adults who never got a solid grounding in free-market economic principles . This Manual is intended to guide the teacher through the course, giving the broader context of the material in the stu- dent text, as well as offering suggested test questions and fur- ther activities . It can be used by classroom teachers, but is also ideally suited to homeschooling instruction by parents who may not be confident in their own economics knowledge . Here’s how the Manual works: First, before introducing a particular chapter (or Lesson), the teacher needs to read it in the student text . Then, the teacher should read the accompa- nying material in the Manual . For each section of each chapter, the Manual.
