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;

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.

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.

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.

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.

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.

These sheets are similar to those on this page but involve only adding or only subtracting numbers using a number line for support.

They are mainly aimed at first and second graders.

Use these sheets to help you add numbers within 10, 20 or 100.
