Add Subtract 3 Terms Practice Activities
Printable math drills for practising three-term addition and subtraction expressions using the left-to-right order of operations.
Practice that builds confidence
What this skill builds
These printable math drill worksheets help children practise expressions with three numbers connected by plus and minus signs, such as 18 - 7 + 4 or 6 + 9 - 5. The focus is reading the whole expression, working from left to right, and keeping each operation sign attached to the next number.
Activities include rows of mixed add/subtract problems, clear answer spaces, and practice sets that build fluency without introducing multiplication, division, or parentheses. Children strengthen mental math, written working, and checking habits for order of operations with equal-priority operations.
Three-term add/subtract practice is an early order of operations skill. Because addition and subtraction have the same priority, children do not add first just because a plus sign appears. They solve in the order the expression is written, carrying each intermediate answer into the next step.
How the practice progresses
The worksheets keep the structure focused: number, sign, number, sign, number. This helps children notice whether the second operation is addition or subtraction and prevents the habit of treating every expression like a simple fact family. Problems may be solved mentally, with quick notes, or by writing a small middle step, for example 18 - 7 + 4 becomes 11 + 4.
Parent practice routine
At home, ask your child to read one expression aloud before solving it. Have them cover the last term, solve the first two numbers, then uncover the final term and use the next sign. After every few problems, invite them to explain one answer using the words first, next, plus, minus, and equals.
Classroom uses
Teachers can use these pages for warm-ups, math centers, fluency folders, or quick checks before moving into longer order of operations expressions. They also work well for small-group reteaching when students know addition and subtraction facts but rush through multi-step expressions.
Common errors to watch for
A common mistake is adding the two positive numbers first in a problem such as 15 - 6 + 2, which changes the meaning of the expression. Some children also subtract both later numbers, ignore the second sign, or copy an intermediate answer incorrectly. Encourage a child-friendly strategy: solve the first pair, write the result, point to the next sign, then finish.

Why iBloom worksheets help
The iBloom practice is intentionally narrow, so children can concentrate on left-to-right reasoning rather than being distracted by new operations. Clear spacing, repeated formats, and mixed plus/minus patterns help build accuracy, confidence, and flexible mental math.
Helpful answers
Frequently asked questions
Why do children solve addition and subtraction from left to right?
Addition and subtraction have equal priority in order of operations, so a three-term expression is solved in the order it appears from left to right.
Are these worksheets still order of operations practice without parentheses?
Yes. They focus on the order rule for equal-priority operations, which is an important step before children meet expressions with parentheses, multiplication, or division.
How should a child check a three-term add/subtract answer?
They can rewrite the middle step. For example, 18 - 7 + 4 should become 11 + 4 before the final answer is found.
What mistake shows my child needs more practice with this skill?
If your child adds all the numbers, subtracts both later numbers, or solves the plus part first automatically, they need more practice tracking signs and working left to right.
Can these pages be used for mental math?
Yes. Children can solve many problems mentally, but writing the intermediate answer is useful when they are learning the left-to-right routine.
Is this add subtract 3 terms worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this add subtract 3 terms 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 add subtract 3 terms 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.
