I purchased this workbook (and the corresponding book) as supplements to a high school equine science course I have created for my homeschooled daughter. In addition, she is in a dual credit program in college, where she earns high school and college credit at the same time. Because my daughter is an equine science and barn management major as well as a passionate horse lover, this workbook is especially helpful for high school, college, and beyond. The workbook is divided into eight parts: overview; skeleton; ligaments, muscles, and tendons; blood vessels and lymph nodes; the nervous system; the head; the foot; and viscera. Each part is further divided into sections within the eight parts. For example, the skeleton is divided into fifteen sections that cover such things as the pelvic girdle, the thigh and leg, the hock, and the skull. What I really like about the book is that when it is opened, on the right page you see the drawings which are labeled with numbers and letters. Then on the left page the numbers and letters are written along with the identified body parts. When my daughter is trying to learn the parts of the horse or studying for a test, she can look at the drawings and not see the names of the body parts, only the specified letters or numbers. That way, she can practice identifying parts without having to cover up all the names. She can simply cover up the page on the left which lists the names. The workbook can be used as a study guide, practice book, test book, reference book, and even an advanced coloring book. The very detailed pictures and identified parts of the horse are drawn in black and white, not color. I like this feature because I can create assignments in which my daughter can identify various bones, muscles, organs, etc. by coloring them. After high school and college, the workbook can become a part of my daughter's horse reference library. I strongly recommend this workbook for students from high school to college and for current or future horse owners who want to learn more horse anatomy in order to better care for their horses.
