Clayton's book is probably the best of an okay batch. After teaching high school economics for 14 years, and having used Clayton for roughly 8 of those years, I have found the book useful. The problem I have with the book is its non standard sequence of economic topics. This is a result of California State curriculm standards not Clayton. The author makes the best out of a bad situation. Consequently I teach the material in the sequence I prefer. This is okay while teaching supply and demand, and other micro issues. When I hit macro economic subjects it just falls apart. I have to cobble together bits and pieces of chapters to get a sequence resembling anything like a standard college sequence of topics;measurement (national income accounting, inflation, and unemployment), circular flow, determinants of aggregate demand,...etc. But of the text on the adopted list I prefer it
