Rounding, Inequalities, Multiples

Welcome to the Math Salamanders Third Grade Math Practice Worksheets.

Here you will find a wide range of free Math Worksheets which will help your child to learn to round numbers, and use inequalities and multiples.

These sheets have been designed to support your child with their learning of inequalities, multiples and rounding skills.

The sheets are graded in order of difficulty with the easiest sheet coming first in each section.

Using these sheets will help your child to:

- Round numbers to the nearest 10, 100 or 1000;
- Use the symbols > , < , and = correctly for equality and inequality;
- Know what a multiple is and how to use and apply multiples knowledge.

ROUNDING TO THE NEAREST 10

When you are rounding a number to the nearest *10*, it is the *ones* digit that you need to look at.

- If the ones digit is less than 5, the number is rounded down to the previous ten;
- If the ones digit is 5 or more, the numbers is rounded up to the next ten.

Examples

136 is rounded up to 140 because the ones digit is a 6.

394 is rounded down to 390 because the ones digit is a 4.

220 stays the same value because it is already a multiple of 10.

ROUNDING TO THE NEAREST 100

When you are rounding a number to the nearest *100*, it is the *tens* digit that you need to look at.

- If the tens digit is less than 5, the number is rounded down to the previous hundred;
- If the tens digit is 5 or more, the numbers is rounded up to the next hundred.

Examples

354 is rounded up to 400 because the tens digit is a 5.

1629 is rounded down to 1600 because the tens digit is a 2.

1300 stays the same value because it is already a multiple of 100.

ROUNDING TO THE NEAREST 1000

When you are rounding a number to the nearest *1000*, it is the *hundreds* digit that you need to look at.

- If the hundreds digit is less than 5, the number is rounded down to the previous thousand;
- If the hundreds digit is 5 or more, the numbers is rounded up to the next thousand.

Examples

7603 is rounded up to 8000 because the hundreds digit is a 6.

4396 is rounded down to 4000 because the hundreds digit is a 3.

12000 stays the same value because it is already a multiple of 1000.

INEQUALITIES

There are two main symbols used to express an inequality:

- > the greater than symbol;
- < the less than symbol.

One way to remember the symbol is to think of it as a greedy mouth. The mouth will always try to eat the biggest number.

Examples

54 > 39

17 < 25

MULTIPLES

If a number is a multiple of another number, it means that it can be made out of adding groups of the other number together.

Examples

12 is a multiple of 4 because 4 + 4 + 4 = 12 (or 4 x 3 = 12)

27 is a multiple of 9 because 9 + 9 + 9 = 27 (or 9 x 3 = 27)

17 is not a multiple of 4 because it cannot be made by adding groups of 4 together.
