Rounding Numbers

Today we rounded numbers in math class. Here is what I gave the students as a rule:

Find the number you are rounding and underline it.
Example 3,785; Thousands
Underline the 3 because that is in the thousands spot.

Look to the right of that number (circle it) and this number will help you decide if you will round up or round down.
Circle the the 7 because it is right next to the 3.

Is that number higher than 5? If yes then round up by adding 1 to the number you are rounding.
7 is larger than 5 so we will round up. We will add 1 to the 3 and make it a four.

After we round the number, we turn the rest of the numbers into zeros.
So 3,785 rounds to 4,000.

If the number next to the number you are rounding is less than 5 then you round down.
Example: 3,485; Thousands
The number next to the 3 is a 4. 4 is less than 5 so we are going to round down. Here we are keeping the rounded number the same as it was and add zeros.

3,485 rounds to 3,000.
