To illustrate this contention, let’s trace back history. During the ancient times, people taught their children knowledge and skills in order to survive by catching fish or hunting animals for food. They had no formal education during that time, but their children learned and acquired the knowledge and skills for survival. So, during that time, they already had a curriculum which other educators call as, the saber-tooth curriculum. This type of curriculum refers to a kind of curriculum that existed during the ancient times in which the purpose of teaching was for survival.
