Add Subtract Practice Activities
Class 3 maths worksheets for mixed addition and subtraction word problems, helping children choose the correct operation and show clear working.
Practice that builds confidence
Building meaning before calculating
These Class 3 maths worksheets help children practise mixed addition and subtraction word problems, where the operation is not given in the question. Children read short real-life situations and decide whether to add, subtract, or compare quantities.
The printable activities include varied contexts such as money, classroom items, scores, collections, and everyday counts. Each worksheet encourages children to underline key information, write a number sentence, solve accurately, and check whether the answer makes sense.
Mixed add-subtract word problems train children to think before they calculate. Instead of looking for a single clue word, they learn to understand the action in the story: Is something being joined? Is something being taken away? Is one amount being compared with another? This is an important Class 3 skill because the same words can appear in different types of problems.
How the practice progresses
The worksheets move from straightforward situations to questions that need closer reading. A child may first solve a problem about finding a total, then answer one about how many are left, and later compare two quantities to find the difference. Useful vocabulary includes total, altogether, remaining, left, more, fewer, difference, spent, saved, gained, and lost. Children practise turning each story into an addition or subtraction equation and recording the answer with the correct unit.
A simple parent routine
At home, ask your child to read the problem aloud once for the story and once for the numbers. Then use three prompts: “What is happening?”, “What do we need to find?”, and “Will the answer be bigger or smaller?” Encourage drawing a quick bar, circles, or a part-whole box before writing the number sentence. After solving, have your child explain the answer in a full sentence, such as “There are 48 books left.”
Classroom uses for teachers
Teachers can use these printables for warm-ups, guided maths groups, revision after addition and subtraction lessons, or independent problem-solving practice. They also work well for pair discussion: one child explains the operation choice while the other checks the calculation and final statement. Completed sheets give useful evidence of whether a child’s error is in reading, choosing the operation, or carrying out the arithmetic.
Common errors to watch for
Some children add every number they see, even when the question asks what is left. Others subtract in the order the numbers appear instead of thinking about the larger and smaller quantity. Watch for missing units, copying a number incorrectly, or answering a comparison question with only one of the given numbers. If a child gets stuck, cover the numbers first and talk only about the situation.

Helpful answers
Frequently asked questions
What do children practise in these Class 3 add-subtract worksheets?
Children practise reading mixed word problems, deciding whether to add or subtract, writing a suitable number sentence, calculating the answer, and giving the answer with the correct unit.
Why are mixed addition and subtraction problems harder than regular sums?
In regular sums, the sign is already given. In mixed word problems, children must understand the story first and choose the correct operation before they calculate.
Should my child rely on clue words like altogether or left?
Clue words can help, but they are not enough. Children should ask what is happening in the problem and what needs to be found, because the same word can appear in different situations.
How can I help if my child adds all the numbers in every problem?
Ask your child to cover the numbers and retell the situation in words. Then ask whether the answer should show a total, an amount left, or a difference between two quantities.
Are these worksheets useful for revision before a maths test?
Yes. They are useful for revising how to identify addition and subtraction situations in word problems, check calculations, and write clear final answers.

Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
