Encourage each pair to measure as many things or in as many ways as possible. Keep an eye out to be sure that everyone is on task. Pair the students and allow them to move about the stations freely. Give them some time to brainstorm, and record their ideas.ĭay 2: Have as many of the students' brainstormed items as possible arranged in stations throughout the room. Are they surprised at how big it is? Tell them that your class is going to make a book like How Much is a Million? about 100, and that they need to think of things to count and measure.
When you finish, ask the students what they think about one million. Put the jar down and read How Much is a Million? by David M. Exaggerated guesses lead into the reading of the story. Without a doubt, some of the answers will be very large. You are likely to receive all sorts of answers accept all guesses, and do not reveal if any are close to the correct answer. Schwartz, 1985īooks, popsicle sticks, blocks, or other things to countĭay 1: Begin class by asking students to guess how many objects are in the jar. Jar filled with 50-100 of the same object Describe their measurements of 100 using words and pictures. Measure 100 in terms of dimension, time, personal reaction, or other appropriate means.Ģ. Number sense is an important asset in estimation activities because it enables students to formulate appropriate approximations.Īs a result of this lesson, the learner will:ġ.
This understanding of the value of a number is termed number sense and can be developed by allowing students to experience 100 by counting it, measuring it, feeling it, and doing it, hands-on. This activity is intended to provide students with the opportunity to discover the magnitude of the number 100.
