2nd Grade Math Worksheets on Rounding Numbers
Kids in 2nd grade math should begin learning the basic rounding. Rounding numbers to tens, to hundreds and thousands is in the basics of rounding the numbers.
Rounding Numbers - Tips For Grade Two Students
In grade two math, kids can start learning rounding numbers. Rounding is very helpful in estimating many big numbers or some times rounding is needed to represent the answer of a problem. Kids in grade two can start rounding numbers from rounding to nearest ten. To learn rounding to nearest tens, kids should know skip counting by tens and place value to tens. Make sure kids are very comfortable with these two skills before starting rounding numbers.
There are following steps for rounding to nearest tens.
1. Ask kids to focus on ones and tens place of the number only (last two digits at far right).
2. Ask the kids to underline the tens digit.
3. Once kids have underlined the tens digit, ask them to look at ones digit.
4. If the ones digit is 0, 1, 2, 3, 4, then keep the tens digit and make ones digit zero if it is not zero already. It is called rounding down.
5. If the ones digit is 5, 6, 7, 8, 9, then ask the kids to add one to the tens digit and make ones digit zero. This is called rounding up.
Example of rounding down: Round 523 to nearest tens.
1. Ones and tens digits are "3" and "2" respectively. Underline the tens digit which is "2" in the given number "523".
2. Now look at ones digit, which is "3" (one of 0 to 4), hence keep the tens digit and make ones digit zero.
3. The rounded down number is "520"
Similarly kids can round to nearest hundreds, by underlining the hundreds digit and deciding to round up or down by looking at tens place digit. Kids in second grade can practice more rounding skills by using 2nd grade math worksheets and practice rounding numbers to make them perfect in this key skill.
