Before & After: A Book of Nature Timescapes by Jan Thornhill
4 pieces of chart paper for time charts. See Materials Preparation.
drawing paper and crayons or markers, optional

Materials Preparation

Prepare Time Charts. Title and display eight separate sheets of chart paper as follows: About One Minute; About a Few Seconds; About Five Minutes; About One Hour; About One Day; About One Week; About One Month; and About One Year.

Prepare Optional Targeted Practice. Place the following items in a learning center for students to practice connecting the passage of time to an event or activity: drawing paper, crayons or markers, the display of the Tree 1–8 Master or a book about the passage of time. Suggested books that discuss the passage of time are: Before and After: A Book of Nature Timescapes by Jane Thornhill, Just a Second: A Different Way to Look at Time by Steve Jenkins, and A Second is a Hiccup: A Child's Book of Time by Hazel Hutchins.

Ask students to fold their drawing paper in half and select a time interval (a few seconds, one minute, five minutes, one hour, one day, one week, one month, or one year). Then ask students to draw two pictures showing an event that illustrates that time interval. On one half of the paper, students should draw the event at the start of the time interval, and on the other half, draw the event after the time interval passes. Encourage students to also write or tell a story about their pictures. Create a bulletin board or an area of the room where students can display their pictures under the appropriate time interval.

Recognize that the measure of a length is dependent on the size of the unit of measure (e.g., a pencil is 4 large paper clips or 6 small paper clips).
