This 23” x 34” timeline can be used intact, or cut into strips to form a 21- foot line. 2½” space between lines allows plenty of room for recording dates, symbols, or small pictures. Front side contains dates from 4000 BC to 2000 AD on 12 lines. Back side is undated, allowing you to tailor-make timelines to fit specific needs (such as a timeline of the student’s life, showing important or memorable events!). It would be interesting for each student to keep a paper timeline each school year and record key people and events from all subject areas. Looking back on them later would trigger memories of each school year!
