Subtract 1-digit decimals in columns

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently, using a partner or small group only if they want to talk through their thinking, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These subtract 1-digit decimals in columns worksheets work well as daily practice, homework, or a focused review activity.

These subtract 1-digit decimals in columns worksheets for 3rd grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter subtract 1-digit decimals in columns from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 3rd grade. Practicing subtract 1-digit decimals in columns at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

Yes, both. We made it for 3rd Grade fractions and decimals, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with subtract 1-digit decimals in columns. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Align the decimal points of both numbers vertically - this ensures tenths are subtracted from tenths and ones from ones, preventing place value errors.

If the tenths digit of the minuend is smaller than the tenths digit of the subtrahend, students borrow 1 from the ones column, adding 10 to the tenths place before subtracting.

Add the answer back to the bottom number (subtrahend) in column form - if the sum matches the top number (minuend), the subtraction was performed correctly.

1 printable worksheet, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 3rd Grade students, roughly ages 8-9. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the Common Core code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.

Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 3rd Grade classroom, a literacy centre, or a tutoring session.
