The Importance of Learning to Round Numbers
Learning to round numbers is a very important skill which students will use throughout their math education and into later life.
Rounding decimals up to the nearest whole number can make adding up several numbers faster and easier. This is particularly useful when shopping; by rounding the prices of items to the nearest pound, the total value of the shop can be quickly estimated. This can be helpful to work out if you have enough money to buy all the items on your shopping list. Rounding might also be useful when estimating distance.
Application of Rounding Numbers in Maths
It is not always necessary to be exact. Some maths questions students come across in their education will result in an extremely long decimal number.
These numbers are very confusing to use in any subsequent calculations, so they are often rounded to make them easier to work with. Hence why instead of writing 3.1415926535 and so on for Pi, we often work with 3.14. This reduces the accuracy of the final answer, but it makes the calculation much simpler. Students will often be required to leave an answer to two decimal places, which involves rounding. In order to be successful in maths, especially at higher levels, students need to be confident on how to round both decimals and whole numbers. Rounding worksheets and activities can help to build confidence and improve technique in this area, preparing children for harder maths questions and later life.
ROUNDING NUMBERS TO THE NEAREST 10
Rounding numbers to the nearest 10, means that you will need to find which 10 is the nearest to the given number. Example: Roundup 48 to the nearest 10. The nearest 10 to the number 48 is 50.
Rules you will have to follow to round up numbers to the nearest ten:
1. Numbers that end up in 1, 2, 3 or 4 we round down.
2. Numbers that end up in 5, 6, 7, 8 or 9 we round up.
With our math worksheets, your child or pupil will quickly develop skills to round up numbers to the nearest ten.
