Richards and Adams begin with a preface (directed, presumably, at teachers) that includes suggestions for social studies tie-ins to yoga activities--e.g. field trips to a yoga studio, projects on ""where do yogis live?"" and ""what do they eat?"" Otherwise this is very basic yoga aimed at ""middle graders"" . . . and with the bridge, windmill, cobra and bow the most difficult poses taught here, it looks even younger. Young children hardly need their own book to learn such easy postures, especially at $5.95 apiece, and teachers who have seen Ruth Ricahrds' earlier collaboration with Erene Cheki. Haney (Yoga for Children) will be disappointed.
