2nd Grade Writing Subtraction Sentences Worksheet: Turn Each Story into Math

Ask a seven-year-old how much change you get from $300 for a $252 duvet, and they may answer with a number but no idea how they got it. Writing the thinking down is the next step, and this 2nd grade writing subtraction sentences worksheet asks for exactly that. Eight stories fill the page. For example, Josiah has 916 tickets to sell for his coach, a reader works through an 800-page book, Jerry saves money over two days, and a spelling bee counts boys and girls. Each story ends with the same request: write the subtraction sentence that fits. Every story uses 3-digit numbers, up to 999. A boy with an open songbook smiles from the top corner. A second page gives the answer key.

Why the sentence comes before the answer

A subtraction sentence like 916 − 439 = 477 is a tiny summary of a whole story. It says what you started with, what changed and what is left. So when children write it, they show that they understood the story, not only that they can subtract.

This page mixes several kinds of subtraction word problems. Some ask what is left, like the tickets. However, others compare two amounts, like the shoes and the handbag, and one asks for the change from $300, which is making change.

The book problem is the richest. It gives three numbers and two questions, so your child must decide which pair belongs to each. The answer key follows the same pattern every time: name each quantity, then subtract.

At the table: the book with 800 pages

Item 2 is where most children stall. The story gives 800, 284 and 95, and a child may write 800 − 95 for the first question. Instead of correcting, ask, "Is question a about the whole book or the pages you read?"

For item 4, the duvet, a child may add $252 and $300. Ask, "Did the cashier give money back or take more?" Then the thinking usually turns around.

Item 8 compares two prices, and the word "more" can trick a child into adding. Point to both prices and say, "Which one costs more? By how much?"

Finally, have your child read each finished sentence aloud with its units. Hearing it helps.

After the page: write the story you see

Life offers subtraction sentences all day. At the store, pay with a bill and let your child work out the change before the cashier does. Also, at home, while reading a chapter book together, check how many pages remain and write it as a sentence on a sticky note.

For a quick game, play I Spy with prices: "I spy something that costs less than $5." Then your child writes how much change a $5 bill would bring back.

Once you finish checking the answer key, name the effort out loud: "You wrote the whole sentence, not just the number." That shows clear thinking.
