Number Line Addition and Subtraction

Welcome to our Number Line Addition and Subtracting page.
Here you will find a selection of free printable addition and subtraction worksheets, which involve using a number line to add or subtract a single digit from a range of numbers.

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

Number Line Addition and Subtraction

Using number lines is a great way to understand addition and subtraction and to physically count on or back 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 and subtraction problems by counting on or back the required number of ones.

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

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

  • add or subtract a single digit from numbers within 10, 20 or 100 using a number line;
  • use a number line to find a missing addend or subtrahend;

Number Line Addition and Subtraction Examples

These examples show how to add subtract 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 or subtrahend.

Example 1)
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.

adding on a number line example 1

This gives us: 6 + 3 = 9

Example 2)
Use the number line below to work out 17 − 4.

We need to start at number 17.

We need to count (or jump) back 4 ones.

subtracting on a number line example 2

We end up at 13.

This gives us: 17 − 4 = 13

Example 3)
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.

adding on a number line example 3

This gives us: 57 + 6 = 63

Example 4)
Use the number line below to work out 73 − 5.

We need to start at number 73.

We need to count (or jump) back 5 ones.

subtracting on a number line example 3

We end up at number 68.

This gives us: 73 − 5 = 68

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.

adding on a number line example 5a

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

adding on a number line example 5c

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

This gives us: 38 + 5 = 43

Example 6)
Use the number line to find the missing number: 54 − ___ = 47.

subtracting on a number line example 5a

Our first step is to start at number 54 and complete the number line back to 44 (we could stop counting back when we get to 47 if we wanted to).

subtracting on a number line example 5b

We need to count (or jump) back by ones until we get to number 47.

subtracting on a number line example 5c

We needed to count back (or jump back) 7 ones.

This gives us: 54 − 7 = 47

Number Line Addition and SubtractionWorksheets

Our worksheets focus on adding and subtracting within 10, within 20 and within 100.

The sheets get gradually harder as you progress through them with less support and more challenging questions.

Number Line Addition and Subtraction within 10 Worksheets

These sheets involve using a number line to add and subtract within 10.

Sheets 1 to 3 involve working out the missing answer (or difference) to a range of subtraction facts.

Sheets 4 involves finding the missing subtrahend when the 'answer' or difference is known and has two versions:

  • Sheet 4A has a completed number line for extra support
  • Sheet 4B has an empty number line for more independent learners.

Number Line Addition and Subtraction within 20 Worksheets

These sheets involve using a number line to subtract within 20.

Sheets 1 to 3 involve working out the missing answer (or difference) to a range of subtraction facts.

Sheets 4 involves finding the missing subtrahend when the 'answer' or difference is known and has two versions:

  • Sheet 4A has a completed number line for extra support
  • Sheet 4B has an empty number line for more independent learners.

Number Line Addition and Subtraction within 100 Worksheets

The sheets in this section involve subtracting a single digit from a two-digit number together within 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 subtrahend when the first number and the difference are known.
