About this printable
A cover, six story-problem practice pages, and the matching answer key make up this 13-page US Letter file. Practice pages 2, 3, and 7 each contain six questions with answer blanks. Situations describe supplies lost, objects added, or pages read on consecutive days; all values stay within 100. More practice pages use these addition and subtraction story types. Name and Date lines are provided. The answer key is on pages 8 to 13.
Turning a story into an operation
A word problem describes a situation, and the operation depends on how the quantities relate. When an amount grows because something is added or two groups are combined, addition can find the total. When some items leave or are used, subtraction can find what remains. Learners should identify what the question asks before choosing an operation; words alone can mislead if they are read without the whole story.
For a story about reading 36 pages one day and 27 the next, the two amounts belong together, so 36 + 27 gives the total pages. For 88 pencils with 27 lost, the starting collection shrinks, so 88 − 27 gives what is left. Drawing a quick bar or writing a number sentence helps connect the story to its quantities. Then estimate whether the answer should be larger or smaller than the starting amount.
Worked example 1
A class had 88 pencils. 27 were lost. How many are left?
The starting set loses 27, so subtract: 88 − 27. Take away 20 to reach 68, then 7 more to reach 61.
Answer: 61 pencils
Worked example 2
Ava read 36 pages Monday and 27 Tuesday. How many altogether?
The two reading amounts are joined: 36 + 27. Add 20 to 36 to get 56, then 7 more to get 63.
Answer: 63 pages
Worked example 3
There were 32 books on a shelf. The teacher added 65. How many in all?
Adding books increases the collection, so calculate 32 + 65: 32 + 60 = 92, then add 5.
Answer: 97 books
How to teach this skill
Act out what changes
Use counters to represent a story collection. Remove counters when pencils are lost; add them when books arrive. Ask the learner to describe the change before writing a subtraction or addition sentence, explaining whether the collection grew or shrank.
Draw a two-part bar
Sketch one bar for the starting amount and mark a part that leaves or a new part that joins. Label the unknown as what the question asks for. A bar diagram can clarify the relationship when the story uses different everyday words.
Retell before calculating
Have the child retell the story in their own words and identify the starting amount, the change, and the unknown. This guards against selecting an operation just because a familiar word appears in the sentence.
Estimate the direction
Before computing, ask whether the answer should be greater or less than the starting amount. A story that adds 30 stickers should grow; one that loses 27 pencils should shrink. Use that prediction to check the completed number sentence.

Classroom and home ideas
Sort stories by change
Read a few situations and sort them into “amount grows” or “amount decreases.” Then name the operation and explain which quantities connect to the question.
Connect arithmetic to context
After solving, include the object or unit in the answer: 63 pages or 61 pencils. Matching the result to the story helps children check what the number represents.
Practice reading for the unknown
Ask students to underline what each story is asking before choosing an operation. This keeps the question, rather than one keyword, at the center of the solution.
What usually goes wrong
Answering 115 for the story where 27 of 88 pencils are lost by adding 88 and 27.
The collection decreases, so subtract the lost amount from the starting count: 88 - 27 = 61. Retell the action with counters before choosing an operation.
Getting 9 pages by subtracting 27 from 36 in the two-day reading story.
Both reading amounts contribute to the total pages. Add 36 and 27 to get 63. A bar with two parts joined into one whole can show why the amounts are combined.
Answering 65 books when a shelf starts with 32 and gains 65 more.
The question asks for all books, including the 32 already on the shelf. Add 32 + 65 to get 97 books, then check that adding makes the collection larger.
Writing 88 stickers for 80 stickers plus 18 more by adding only the 8 ones.
Add both parts of 18 to 80: first add 10 to reach 90, then add 8 to reach 98. The final amount is 98 stickers, not 88.
Questions people ask
How do you solve addition and subtraction word problems to 100?
Read the whole story, identify the starting quantities and what changes, then decide whether the amount joins or decreases. Write an equation and solve it. Finally, compare the answer with the story: adding should increase a total, while taking away should leave fewer items.
How can I teach children to choose addition or subtraction in a story?
Ask them to retell the situation and say what happens to the amount. Use counters or a bar drawing to show items joining or leaving, then write the matching equation. Have children explain why that operation fits the question rather than pointing only to a keyword.
How do you check addition and subtraction word problems?
Check both the calculation and the situation described. Lost pencils should leave fewer than the starting count; books added to a shelf should make a larger total. Include the object or unit in the response, then reread the question to confirm that the number answers it.
