Welcome to our Adding on a Number Line Worksheet page.

Here you will find a selection of free printable addition worksheets, which involve using a number line to add up a range of numbers.

These worksheets have been designed for children working at a first or second grade level.

Using number lines is a great way to understand addition and to physically count on the correct number of ones required for the answer.

The sheets on this page have been designed for 1st and 2nd graders to help them understand how to work out addition problems by counting on the required number of ones.

There are two main ways to use a number line for addition:

- Method 1 is to start at zero, count the first number in ones, then count on the second number in ones.
- Method 2 is a more efficient way which is to start at the first number (not zero) and count on the second number in ones.

Both of these methods can be seen below.

When children first learn to count along a number line they tend to use Method 1.

However, when this method has been learnt and understood, Method 2 should be introduced as a better and more efficient way to add using a number line.

On this page, we have a range of worksheets to develop counting along a number line within 10, 20 and 100.

There are 2 versions of each sheet:

- Version (a) which is based on Method 2 to count on from the first number and is a more supported sheet
- Version (b) has a blank number line so that any method can be used and requires more work from the child to answer

Using these adding on a number line worksheets will help your child to:

- add numbers within 10, 20 or 100 using a number line;
- use a number line to find a missing addend;

These examples show how to add on a number line within 10, 20 or 100.

We also have several examples showing how to use a number line to find a missing addend.

Use the number line below to work out 6 + 3.

We need to start at number 6.

We need to count (or jump) on 3 ones.

This gives us: 6 + 3 = 9

Use the number line below to work out 9 + 7.

We need to start at number 9.

We need to count (or jump) on 7 ones.

This gives us: 9 + 7 = 16

Use the number line below to work out 57 + 6.

We need to start at number 57.

We need to count (or jump) on 6 ones.

This gives us: 57 + 6 = 63

Use the number line to find the missing number: 3 + ___ = 7.

We need to start at number 3.

We need to count (or jump) on by ones until we get to number 7.

We needed to count on (or jump) 4 ones.

This gives us: 3 + 4 = 7

Use the number line to find the missing number: 38 + ___ = 43.

We need to start at number 38 and fill in the number line up to 43.

We need to count (or jump) on by ones until we get to number 43.

We needed to count on (or jump) 5 ones.

This gives us: 38 + 5 = 43

The sheets in this section involve adding two numbers together within a total value of 10.

Sheets A and B are identical, but sheet A offers more support.

Sheet 4 is a trickier sheet which involves using a number line to find the missing addend when the first number and the total are known.

The sheets in this section involve adding two numbers together within a total value of 20.

Sheets A and B are identical, but sheet A offers more support.

Sheet 4 is a trickier sheet which involves using a number line to find the missing addend when the first number and the total are known.

The sheets in this section involve adding two numbers together within a total value of 100.

Sheets A and B are identical, but sheet A offers more support with a pre-filled number line; sheet B has an empty number line.

Sheet 4 is a trickier sheet which involves using a number line to find the missing addend when the first number and the total are known.
