rounding decimals

This week in 5th grade math, we are working on all numbers including numbers with decimals.  


Rounding with a Vertical number line.  A vertical number line is the same as a regular number line except that it runs vertically instead of horizontally.  When rounding, there are two saying that are used to help students know when to round up or stay the same.

The first example is as follows:                                       

5 or more, raise the score                                                     

4 or less, let it rest                                                                        

The second example is as follows: 


Bossy numbers: 5, 6, 7, 8, and 9 

Bossy numbers push the line leader forward 1 place 

Non-bossy numbers: 0, 1, 2, 3, and 4

Non-bossy numbers tell the line leader to stay the same


Steps when rounding numbers:

1) Underline the place value that you are rounding to

2) Circle the number to the right of the underlined digit

3) Determine if the number that is circled is a bossy or nonbossy number.

4) Round the number according to step 3

5) The circled number becomes a zero

In class, we have started our study of vertical number lines.  Watch this video to better your understanding of how to round by clicking on the link below.
