Adding on a Number Line Worksheets

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.

Adding on a Number Line

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.

adding on a number line methods

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;

Example 4)
Use the number line to find the missing number: 3 + ___ = 7.

We need to start at number 3.

adding on a number line example 4a

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

adding on a number line example 4b

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

This gives us: 3 + 4 = 7

Example 5)
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.
