Order Operations Add Sub 4 Practice Activities
Grade 3 worksheets for solving four-number addition and subtraction expressions in the correct left-to-right order.
Practice that builds confidence
What this skill builds
These Grade 3 math worksheets help children practise order of operations with addition and subtraction only. Students learn that when the operations have the same priority, they solve the expression from left to right, not by doing all additions first.
The printable activities include multi-step number expressions with four numbers and a mix of + and − signs. Children work through each expression carefully, record intermediate answers, and build accuracy with math vocabulary such as expression, operation, sum, difference, and left to right.
Order of operations can feel new in Grade 3, but this page focuses on a clear starting point: addition and subtraction in the same expression. Because these two operations have equal priority, children should work in the order the numbers and signs appear. For example, in 18 − 5 + 4, the first step is 18 − 5, then the result is added to 4.
How the practice progresses
The worksheets give children repeated chances to read a complete expression before calculating. They practise handling four numbers in a row, keeping track of partial answers, and noticing how a different order can change the final result. This is an important foundation before children meet more complex order of operations questions involving other operation types or grouping symbols.
Parent routine for home practice
Sit with your child for the first few problems and ask, “What is the first operation you see from the left?” Have them underline only that first step, solve it, and rewrite the shorter expression. Continue until one number remains. If a mistake happens, avoid erasing everything at once; compare the written steps to the signs in the original expression and find the exact place where the order changed.
Classroom uses for teachers
Teachers can use these printables as independent practice, morning work, math centers, or a short check after introducing left-to-right evaluation. They also work well for partner review: one student reads the expression aloud while the other explains each step. This helps students connect written symbols with mathematical language.
Common errors to watch for
Many children try to add first because addition feels easier or more familiar. Others skip rewriting the expression after each step, which can lead to dropped signs or copied numbers. Watch for answers that come from solving right to left, grouping numbers mentally, or changing subtraction into addition without a reason.

Why iBloom worksheets help
The iBloom activities keep the focus narrow: four-number addition and subtraction expressions, clear spacing, and enough repetition to build fluency without mixing in unrelated skills. A child-friendly strategy is: “Point to the left, solve one sign, write the new line, then keep moving.” This simple habit builds confidence and prepares students for longer order of operations work.
Helpful answers
Frequently asked questions
What order should children use when an expression has only addition and subtraction?
They should solve from left to right because addition and subtraction have the same priority in order of operations.
Why are four-number expressions useful for Grade 3 students?
They give students enough steps to practise tracking the order carefully while still staying within an addition and subtraction focus.
Should my child do all the additions before the subtractions?
No. In expressions with only addition and subtraction, doing all additions first can change the answer. The correct habit is to move from left to right.
How can I help if my child keeps losing a sign?
Ask them to rewrite the expression after each step and circle the next operation before solving. This makes each sign visible and reduces copying errors.
Are these worksheets for multiplication and division order of operations?
No. This collection focuses specifically on addition and subtraction expressions, which is a helpful early step before mixed-operation order of operations.
Is this grade 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 grade 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 grade 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.
