How To Learn Rounding Numbers.

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.

Subtraction Worksheets - 2nd grade math worksheets for kids

Introducing Subtraction To Kids Using Subtraction Worksheets  

Kids in grade one need to learn how to subtract one digit numbers. Subtraction is also known as take away and it is very important that kids in elementary grades master this skill.
The basic part of subtracting numbers can be taught to kids using models. Parents can use many things from daily life as models. For example, a bunch of bananas can be used. From kitchen spoons and forks can be used.
There are many more daily life objects which can be used to introduce kids with subtraction. In this presentation we will use the example of bananas.
Get a bunch of bananas from the kitchen and ask the kids to count all of the bananas in it, and consider there are six bananas in the bunch. Now ask one of the kids to pull away one banana and hide it. After that, ask the kids to count bunch of bananas again, this time they will count five bananas in the bunch. Stop there and explain the kids about take away, which means, subtracting number of things and in your example, six take away one is five.
Use lots of examples with other objects from daily life as in the example above. After kids get the idea of take away using concrete examples, the next step is to use subtraction worksheets on basic subtraction with visual shapes. Now you can use pictures of bananas instead actual ones, kids will understand it.
Once kids get the concept of subtraction using shapes, and have learned subtracting numbers by cutting shapes then you can start using numbers instead shapes.
Now get ready to teach your kids subtracting one digit numbers (0 - 9). Following is an example I use to introduce subtraction to my kids and students;
Ask kids to find "5 - 2"
Solution: To do this ask kids to draw five lines as shown below:
/ / / / /
Out of these five lines, now ask kids to erase or cut two lines ( because two is getting subtracted from five) as shown below:
/ / /
Now there will be only thee lines left as shown above, ask kids to count the remaining lines to get their answer, which is three.
Finally ask them to write the subtraction fact as shown below:
"5 - 2 = 3"
Similarly, repeat all the one digit subtraction facts with kids many times, until they are very good at it. Keep it up until they start doing it using their memory without drawing lines and cutting or erasing them.
You can use subtraction worksheets for extra practice and to teach basic subtraction to your kids. Soon, you will find your kids with very strong subtraction skills.

Soon there will be more tips on 2nd grade math and we are updating our site for 2nd grade math worksheets on a regular basis. Parent can print more math content for kids in grade two at our site.
