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.
