Your teacher will assign a set of numbers to you. 

1. Several number lines are posted around the room. Work with your group to decide on which number line each number should go.

   Then estimate the location of the number on the line, put a dot sticker to mark it, and label it with the number.

2. Look at the number line that represents 0 to 100,000 and has 2 points on it.

   1. Name 2 multiples of 10,000 that are closest to each point.
   2. Of the 2 multiples of 10,000 you named, which one is the nearest to each point?

Use the number line that represents the numbers between 100,000 and 200,000 for this activity.

1. Name the multiple of 10,000 that is the nearest to each number. (Leave the last column blank for now.) 

   number	nearest multiple of 10,000
   100,025
   128,201
   140,261
   158,002
   194,030

2. Here is the number line that shows 215,300. Which multiple of 100,000 is the nearest to 215,300?

   

3. Label the last column in the table “nearest multiple of 100,000.” Then name the nearest multiple of 100,000 for each number in the table.
