Borrow over zeros

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Encourage students to talk through their thinking as they work: "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 borrow over zeros worksheets work well as daily practice, homework, or a focused review activity.

These borrow over zeros worksheets for 2nd 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 borrow over zeros from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 2nd grade. Practicing borrow over zeros at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

"Borrow over zeros" is written for 2nd Grade (Ages 7-8), and it covers Common Core 2.NBT.B.5. If your little one is a year younger but already steady on subtraction, the page still works. You may just need to read the instructions out loud. And if they are older and borrow over zeros never quite stuck, this is a short review rather than busywork.

Yes, both. We made it for 2nd Grade subtraction, 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 borrow over zeros. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

When a zero is in the borrowing column, students cannot simply reduce it by 1; they must first borrow from the next non-zero column to the left, then pass that borrowed value through - a multi-step chain.

Students borrow from the 3 hundreds to make 2 hundreds and 10 tens; then borrow 1 ten to make 9 tens and 10 ones; finally subtract 7 from 10 (ones) and 4 from 9 (tens): result is 253.

Explicitly crossing out each digit after borrowing and writing the new value above it helps students track changes step by step without losing the chain of regrouping across zeros.

Second graders should fluently subtract within 20 (CCSS 2.OA.B.2) and subtract within 100 using strategies based on place value (2.NBT.B.5). They also begin subtracting within 1,000 with models and drawings (2.NBT.B.7).

Start with base-ten blocks: show that when you cannot subtract the ones, you trade one ten for 10 ones. Practice this physically before moving to paper. Worksheets that show the regrouping step-by-step help students internalize the process before working independently.
