🏠 Parent Activity: Button Shop
Place 17 large buttons on a tray. Let the child “sell” 6 and count the buttons left. Draw the story and write 17 − 6 = 11 buttons.
Ask what each quantity represents. Return the 6 sold buttons to check the starting collection. For a new challenge, ask how many were sold if 10 buttons remain.
💡 Subtraction Story Learning Tips
Five Parent and Teacher Tips
Read without choosing the operation for the child. Ask for a retelling. Use a model that fits the situation. Distinguish the amount removed from the amount left. Ask the child to check the result.
Six Tips for Students
Read the complete story. Find the question. Identify what each quantity counts. Show what happens. Calculate and label the answer. Check with your model or a related addition fact.

Think about what happens
A subtraction word problems worksheet for Class 1 helps children connect quantities with actions and comparisons. Begin by discussing what is known and what needs to be found. A child may be looking for what remains, what is hidden or how two collections differ.
Choose a model that fits
Move objects out of a group for a taking-away story. Line up two rows and match pairs for a comparison. Represent the whole and visible part when something is hidden. These models help learners explain why a subtraction sentence matches the question.
Read beyond one keyword
“How many more?” can ask for a difference between two known groups. It does not always mean addition. Some stories also contain a number that is not needed, such as the number of trays holding a collection. Decide what each number counts before using it.
Count the jumps carefully
On a number line, begin at the starting quantity. Each backward jump represents one removed object; the starting point is not a jump. Counting up between two quantities can also reveal their difference. Choose a method the child can explain clearly.
Check and continue practising
Label the answer and return to the story to check its meaning. A related addition fact can rebuild the whole from its parts. Use the existing download option for paper practice alongside the online quiz and games. The language selector changes this interactive section, not the downloaded PDF.
💬 Subtraction Word Problems FAQs
What are subtraction story sums?
They are situations where children find an amount left, an unknown part or a difference.
How do I teach subtraction word problems to Class 1?
Read, retell and model the story before writing a number sentence.
Does “how many more” always mean addition?
No. When comparing two known quantities, it can ask for the difference.
Can children use pictures to solve subtraction stories?
Yes. Cross out removed objects or draw aligned rows to compare groups.
How does counting back help with subtraction?
Each backward jump represents one unit removed. Do not count the starting point as a jump.
Can counting up help find a difference?
Yes. Count the steps from the smaller quantity to the larger quantity.
What is a missing-part subtraction problem?
The whole and one part are known, and the other part must be found.
How can children check a subtraction answer?
Add the parts to check that they rebuild the whole.
Does subtracting zero change the amount?
No. If nothing is removed, the quantity stays the same.
What happens when every object is taken away?
No objects remain, so the answer is zero.
What if my child finds the reading difficult?
Read aloud and allow objects or drawings without telling the child which operation to choose.
