Number sense is an important asset in estimation activities because it enables students to formulate appropriate approximations. Measure 100 in terms of dimension, time, personal reaction, or other appropriate means. Describe their measurements of 100 using words and pictures. Improve estimating skills. Without a doubt, some of the answers will be very large.
Exaggerated guesses lead into the reading of the story.
When you finish, ask the students what they think about one million. Give them some time to brainstorm, and record their ideas. Have as many of the students' brainstormed items as possible arranged in stations throughout the room. Pair the students and allow them to move about the stations freely. Keep an eye out to be sure that everyone is on task.
