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.

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 (54 is greater than 39)

17 < 25 (17 is less than 25)

127 > 100+25 (127 is greater than 100+25)

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.

A factor is a number that divides into another number with no remainder.

In other words every number is divisible by each of its factors.

1 is a factor of every whole number, because every integer is divisible by one.

Examples

3 and 7 are both factors of 24 because 3 x 7 = 24

10 and 6 are both factors of 60 because 10 x 6 = 60

7 is not a factor of 24 because 24 is not divisible by 7 (24 ÷ 7 = 3 remainder 3).

Multiples and Factors are connected with each other:

- if we know that 3 is a factor of 12, then 12 is a multiple of 3
- if we know that 33 is a multiple of 11, then 11 is a factor of 33.
- likewise, if we know that 24 is not a multiple of 7, then 7 is not factor of 24.

The example below shows the relationship visually.

If we know that 3 is a factor of 24, then 24 must be a multiple of 3.

If we know that 24 is a multiple of 3, then 3 must be a factor of 24.
