# Number,place value, rounding, approximation, estimation for Kids

*(scroll this section to read all)*

Learning about numbers and in particular place values is absolutely essential to your understanding of mathematics. A sound understanding of this by around the age of 8 is very important since this is a key building block for the math subject. Also knowledge of rounding and estimation is really useful in real life situations where you can quickly make a decision based on approximate data and calculations as well as improving the speed you learn math and it will probably help you understand a problem more deep and help develop your visualization skills.

And we all know that being good at math is useful in everyday life as well as being needed in virtually every job and especially in many highly paid ones.

Once you understand the basics of numbers, place values, rounding and estimation, you should be able to:

- Read, write, speak and count from 0 to 100 forwards and backwards (initially in 1's , 2's , fives and tens but later in any number)
- Understand equals, more than and less than concepts
- Recognise and understand place value initially in 2 digit numbers but later in very large numbers
- See patterns and sequences in numbers, shapes and colours
- Use estimations for addition and subtraction sums using rounding as a strategy
- Use comparisons and order numbers
- Understand how larger numbers can be represented in different ways
- Solve problems using numbers, rounding and estimations as appropriate
- Become familiar with the decimal system
- Understand how Roman Numerals work
- Understand and use negative numbers in calculations and graphing.

You will notice that below we have made a superb list of links for you to follow to really get to grips with place value, rounding and estimation. We have lots of videos, games and activities which will make learning this subject really enjoyable. Give them a try!
