A simple fact of knowing the difference between day and night would be a childâ€™s first understanding of time. As children grow, they develop a profound understanding of time and the way it affects our lives. By learning about the concepts of past, present and future, a child begins to place a logical order into their lives and begin to make sense of the things that are happening around them. This chapter inculcates a basic skill in children which they retain for the rest of their lives.
