This free printable focuses on subtracting multiples of ten and is aligned to 1.NBT.C.6. Every new set keeps the same grade-level goal while changing the numbers or visual models, so students can practice again without repeating the exact page.
The worksheet moves through three parts: Explore the idea, Build your skills, and Apply your thinking. Students meet the concept, complete focused questions, and use it in a model, explanation, or short problem. A matching answer key is generated from the same set.
Count backward by tens and track only the tens digit. Check the result by adding the subtracted tens back.
Choose New problems whenever another version is useful. Select the worksheet, answer key, or both, then print or save the pages as a PDF. The layout is designed for one-page practice on US Letter and A4 paper. These worksheets are free for home learning, tutoring, and classroom instruction.
