At the primary level, EVS is an integrated subject area that incorporates knowledge from the sciences (physical, chemical, and biological), social studies (history, geography political science, and so on), and environmental education (protection and conservation).There are no prescribed textbooks for classes I and II because environmental studies are not taught at very primary level (classes 1 and 2) as a distinct subject but the concepts which are important to know at that stage of life are taught through language and mathematics.As children see the world holistically rather than dividing it into distinct subject areas, it is important to provide learning experiences that blur the lines between subject areas. This not only helps to lighten the curriculum load but also helps children to learn more effectively.Hence, we conclude that there are no textbooks of EVS for classes because environmental components have been integrated with language and mathematics.
