Order Operations Add Sub 4 Practice Activities
Printable Class 3 maths worksheets to practise solving addition and subtraction expressions in the correct left-to-right order.
Practice that builds confidence
Understanding the rule
These Class 3 maths worksheets help children practise the order of operations when an expression contains only addition and subtraction. Children learn that + and − have the same priority, so they solve from left to right instead of doing all additions first.
The printable activities include clear number sentences with several add and subtract signs, space for step-by-step working, and mixed practice that encourages careful reading, accurate calculation, and checking the final answer.
In these worksheets, children work with expressions such as 48 − 15 + 9 or 32 + 18 − 7 − 6. Since addition and subtraction are at the same level, the correct method is to start at the left and move one step at a time. This is different from choosing the operation that looks easiest.
Building calculation fluency
The practice begins with straightforward number sentences and gradually encourages children to handle longer add-subtract chains. They strengthen mental maths, column calculation, and number sense while using vocabulary such as expression, operation, plus, minus, difference, total, and left to right.
A simple home routine
Parents can ask the child to read the whole expression aloud, circle the first operation, solve it, then rewrite the shorter expression. For example, 40 − 12 + 5 becomes 28 + 5, then 33. After each answer, ask, “Did you move from left to right?” This short question helps children notice the order, not just the arithmetic.
Classroom use
Teachers can use these printables for guided practice after introducing order of operations, for maths centres, or as a quick independent task. They also work well for board correction: invite pupils to show each intermediate step so the class can compare methods, not only final answers.
Common errors to watch for
Some children add all the positive numbers first and subtract later, which can change the answer. Others skip rewriting steps and lose track of the running total. Watch for sign confusion, especially when two subtraction steps appear in the same expression. Encourage neat spacing and one operation per step.

Why iBloom worksheets help
iBloom activities focus on the exact Class 3 skill: ordering addition and subtraction operations.

A child-friendly strategy is: “Start left, solve one sign, write what is left.”
Helpful answers
Frequently asked questions
What order should children follow for addition and subtraction expressions?
When an expression has only addition and subtraction, children should solve from left to right because both operations have the same priority.
Are these worksheets suitable before learning brackets and multiplication rules?
Yes. This page focuses only on addition and subtraction order, making it suitable for Class 3 learners who are building the foundation for later order of operations work.
What is a common mistake in these problems?
A common mistake is adding all numbers first and then subtracting. For add-subtract chains, children must follow the order in which the signs appear from left to right.
How can parents help if a child rushes through the worksheet?
Ask the child to rewrite the expression after each single operation. This slows the work down and makes the left-to-right process visible.
Can teachers use these worksheets for maths centres?
Yes. They are useful for independent practice, partner checking, small-group reteaching, or quick revision after a lesson on addition and subtraction order.
Is this Class 3 order of operations addition subtraction worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 3 order of operations addition subtraction worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 3 order of operations addition subtraction worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
