This paper explores several published studies regarding the implementation of yoga postures, breathing techniques and guided meditations in low income and/or ethnic minority schools. The possibility for these techniques to meet some of the students' needs of safety, belongingness and self-esteem is considered. Discussion regarding ease and cost of implementation is conducted. The implementation of the curriculum Yoga4Classrooms in a predominately White, middle class, kindergarten classroom is detailed. Several measures are reported, including: the amount of time that the students engaged with the curriculum, the effect of the curriculum on students' behavior, the effects of the curriculum on students' responses to stress and anecdotal accounts of students reactions to the curriculum. Several factors influenced these measures, such as confidence to implement the curriculum and the moral and cognitive development of the students.
