Petroglyphs: Snapchat of Ancient Times

The development of means of communication has impacted man’s ability to relate to others as an individual, as a group, or as a nation. Means of communication have changed from man’s early days to the present but the purposes have not. In this lesson students will learn about one form of communication—petroglyphs. Why and how were they used, and how many other cultures also used this means of communication? This lesson contains strategies for diverse learners (ELLs).
