Teaching Children's Gymnastics - Spotting and Securing
by Ilona Gerling

This is the first book that explains why spotting is valuable, how spotting can be developed methodically and how children spotting each other is supposed to look. Spotting and securing are two essential safety constituents when it comes to teaching and training gymnastics. Teaching Children’s Gymnastics takes a close look at what spotting and securing really means and how it must be done. It is a new, revolutionary teaching idea, which gets even the youngest children to learn how to spot each other safely. Containing step-by-step instructions for teaching children to spot each other, as well as hundreds of examples and suggestions for interactive and spotting gymnastic exercises, Teaching Children’s Gymnastics is an invaluable resource for all teachers, coaches, day camp leaders and others who work with children. more
