Students will have first practiced making a timeline by creating one for their life. Students
are encouraged to look through their own family albums and photographs to determine important events in their lives, with dates such as birthdays, special vacations, first communion, first bicycle, etc. as defining periods.

With a partner or in small groups, each group will interpret a set of vintage photographs of the local community, and using clues from the pictures, organize the photographs in their perception of chronological order. A timeline is created using the photocopied pictures, tag-board sentence strips or posters. A vocabulary list and worksheet are included below.
After these are made, the partners or groups share their timeline and justify the placement of the pictures. Additional templates are available from at

Directions for photographs:
After printing these vintage photos and captions, students cut out, then match sentence strips from the worksheet with them.

After all groups have presented, the instructor will provide the “true” sequence of events, rewarding the group(s) that came closest with their timeline. Below are links to virtual museums focusing on the San Bernardino Mountains communities.

Lake Arrowhead Virtual Museum
Description: Today, Lake Arrowhead is a quiet resort community about eighty miles east of Los Angeles. But it hasn't always been like this. Explore the natural environment and the unique history of the region. Learn how this mountain community changed from the summer home of the Serrano Indians, to a Mormon logging camp, and then to a resort after the damming of Little Bear Valley and the creation of the Arrowhead Reservoir and Power Company. Standards 3.1, 3.2.2, 3.3.2 and 3.3.3.
Comments: How does the development of Lake Arrowhead match with that of other southern California communities?

Big Bear ... Now and Then
Description: Did you know there was a Gold Rush in Southern California? Learn about this and much more in the Virtual Museum of Big Bear. After a brief discussion of the Native Americans who lived in Big Bear in the summer, follow the development of the region through the miners and settlers who followed. Discover how and why the lake was built. Standards 3.2.3, 3.3.1, 3.3.2, and 3.3.3
Comments: Simple reading level with support activities for independent student use.

Students are provided quick feedback as each group self-assesses their timeline as compared to the “true” sequence of events provided by their teacher. Credit/grades are based on participation, oral presentation skills, and the students’ ability to gather information from primary sources by careful observation.
