Help the children think of at least five major events in their life. The first event will be the child's birth. Depending on the age group, more events can be added. For example, children in middle school might be able to think of seven or eight memorable events.
Help the children write these events down on scratch paper in chronological order. Label each event with the corresponding year. Older children can write the events themselves using words of their choice, and may also know the exact month or date of their milestones.
Ask the children to think of a picture to draw for each event.
Draw a table on the poster board using the yardstick. This could be as simple as drawing a large rectangle divided in sections to create a horizontal or vertical series of boxes.
Help the children transfer their events from the scratch paper to the poster board. Draw and color the picture for each event into the appropriate section using pencils, crayons and markers.
