This volume is divided into two books [or "sections"], Book One and Book Two. Both books are written on a fifth-grade vocabulary level so that either one can be used for fifth or sixth grade. The reason for this is so that multi-grade classrooms can combine fifth and sixth grades into one health class. In doing so, you save class time (a precious commodity in a busy classroom), thus giving you more time for the class.
Combining grades means that one year both grades with have Book One; the next year a new fifth grade and last year's fifth students, which are now sixth grade, will have Book Two. Therefore it is important that both books are on the same level (one book is not more important than the other). It is also important that each book is self-contained (they do not depend on each other for information). That way it makes no difference whether a student has Book Two first or Book One. Of course, that makes it necessary to have some facts repeated in both books, but they are given in such different ways that it seems new again. Most knowledge taught in school is repeated and reviewed anyway because that is how the human mind best stores and retains knowledge.
Each book is divided into five chapters. Each chapters is divided into parts. Each part is followed by exercises to be done on paper. (Warn students not to write in their books.) At the end of each chapter is a chapter review. Chapter tests are available in booklet form.
The annotated teacher's edition contains many notes to help the teacher besides all the answers to the exercises and tests. Other activities are also suggested for various lessons, especially in the parts on first aid which needs class practice to be taught properly.
