Order Operations Add Sub 6 Practice Activities
Printable Grade 3 worksheets help students evaluate six-number addition and subtraction expressions by following left-to-right order and any grouping shown.
Practice that builds confidence
What this skill builds
These Grade 3 math worksheets focus on order of operations for expressions that use addition and subtraction, including longer six-number strings. Children practise deciding what to do first, reading symbols carefully, and recording each step so the value of the expression stays clear.
The printable activities include straightforward number sentences, mixed add-and-subtract expressions, and items where students rewrite the expression after each move. Because addition and subtraction have the same priority, the key habit is working from left to right unless parentheses or other grouping is shown.
In this Grade 3 order of operations set, students learn that addition and subtraction are handled at the same level. That means an expression such as a chain of adds and subtracts should be solved in the order it is read, from left to right. Longer six-number expressions give children extra practice holding their place and checking each sign before calculating.
How the practice progresses
The worksheets move from simple mixed addition and subtraction sentences to longer expressions where one skipped sign can change the answer. Some items encourage students to show intermediate steps, such as solving the first two numbers, bringing down the next operation, and continuing. This supports both accuracy and mathematical communication.
Parent routine for home
Ask your child to point to the first operation and say, “I work left to right because addition and subtraction have equal priority.” Have them cover the part of the expression they have not reached yet, solve one step, then rewrite the remaining expression neatly. After the answer is found, invite them to read the original expression again and check whether each plus or minus sign was used in order.
Classroom uses for teachers
Teachers can use these printables for independent practice, math centers, warm-ups, or quick checks after introducing order of operations without multiplication and division. They also work well for partner explanations: one student solves while the other listens for vocabulary such as expression, operation, plus, minus, left to right, and grouping symbols.
Common errors to watch for
Students may add all the numbers first, subtract only at the end, or choose the largest numbers before following the expression order. Others may copy a plus sign as a minus sign when rewriting steps. Encourage children to underline the next operation, not the most comfortable one.

Helpful answers
Frequently asked questions
What rule should Grade 3 students use for addition and subtraction expressions?
When an expression has only addition and subtraction, both operations have the same priority, so students solve from left to right unless grouping symbols show a different order.
Why do these worksheets use longer six-number expressions?
Longer expressions help children practise tracking each operation carefully. They build stamina, accuracy, and the habit of rewriting the expression after each step.
Should my child add all the numbers before subtracting?
No. In a mixed addition and subtraction expression, children should not group all additions first. They should follow the expression from left to right.
How can I help my child avoid sign mistakes?
Have your child underline or point to the next plus or minus sign before calculating. Rewriting the remaining expression after each step also reduces copying errors.
Are these worksheets useful before learning full order of operations?
Yes. They focus on the important foundation that addition and subtraction share the same priority, preparing students for later expressions that include more operation types.
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.
