Order Operations Add Sub 3 Practice Activities
Grade 3 worksheets help children evaluate addition and subtraction expressions in the correct order, including left-to-right thinking and grouping.
Practice that builds confidence
What this skill builds
These Grade 3 order of operations worksheets focus on expressions that use addition and subtraction. Children practice deciding what to calculate first, reading expressions carefully, and keeping each step organized.
The printable activities include multi-step problems, equation-style practice, and space to show thinking. They are useful for strengthening accuracy before children meet order of operations with more operations.
In this Grade 3 math set, children work with order of operations using addition and subtraction. Because addition and subtraction have the same priority, students learn to solve them in the order they appear from left to right, unless grouping symbols tell them to do something first. For example, 18 - 5 + 2 is handled as 13 + 2, not as 18 - 7.
How the practice progresses
The worksheets move from straightforward expressions to items that require more careful tracking. Children may see three-number expressions, missing-step work, or problems where a small change in order changes the answer. This helps them connect vocabulary such as expression, operation, sum, difference, and evaluate with the written work on the page.
A simple parent routine
At home, ask your child to read the whole expression aloud before writing anything. Then have them point to the first operation they will do, solve only that part, and rewrite the remaining expression underneath. After the final answer, ask, “Did you move from left to right?” or “Were there any grouping symbols?” This quick routine turns checking into a habit instead of a last-minute fix.
Classroom uses
Teachers can use these pages for morning review, small-group reteaching, independent math centers, or exit tickets after a lesson on expressions. They also work well for comparing two solved examples: one correct and one with the operations done in the wrong order. That discussion helps students explain reasoning, not just fill in answers.
Common errors to watch for
A frequent mistake is adding before subtracting every time, even when subtraction comes first. Another is trying to combine the last two numbers because they look easier. Some students also copy the answer from one step into the wrong place. Encourage neat vertical step-down work so each line shows one clear change.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
These iBloom worksheets give focused practice without mixing in unrelated skills too soon. The layout supports step-by-step thinking, while repeated addition-and-subtraction expressions help children notice the pattern: same-level operations are solved from left to right. A child-friendly strategy is, “Read it, choose it, solve it, rewrite it.”
Helpful answers
Frequently asked questions
What order should Grade 3 students use for addition and subtraction expressions?
When an expression has only addition and subtraction, students solve the operations from left to right, unless grouping symbols show a different part to do first.
Do these worksheets include multiplication or division?
This page focuses on order of operations with addition and subtraction only, making it a good early step before mixed-operation practice.
Why is 18 - 5 + 2 not the same as 18 - 7?
Addition and subtraction have the same priority, so the expression is solved from left to right: 18 - 5 = 13, then 13 + 2 = 15.
How can my child show work clearly on these problems?
Have your child rewrite the expression after each step, changing only the part that was just solved. This reduces skipped steps and copying errors.
How can teachers use these worksheets in class?
They can be used for warm-ups, math centers, small-group review, partner checking, or short exit tickets after teaching left-to-right order for same-level operations.
