About this Grade 3 Subtraction With Borrowing Drill

Subtraction-with-borrowing—sometimes called regrouping—is a crucial bridge in your child's math journey. At age 8-9, students are moving beyond simple facts to tackle two-digit problems where the ones place isn't large enough to subtract from. This skill directly connects to real-world situations: making change at a store, figuring out how many supplies are left after a project, or calculating the difference between two prices. When students master borrowing, they develop flexible number sense and build confidence for division and multi-digit problems in upper grades. Without this foundation, children often resort to counting on their fingers or become frustrated with math entirely. This worksheet gives your third grader focused practice in the exact strategy schools teach, reinforcing the "borrow from the tens" concept that unlocks so much of elementary mathematics.

What your student will practice

• Regroup tens into ones to subtract when the ones digit is insufficient
• Correctly reduce the tens place by one after borrowing
• Solve two-digit subtraction problems with regrouping
• Apply borrowing logic to solve word problems involving subtraction

Common mistakes to watch for

The most common error is students who forget to reduce the tens digit after borrowing. For example, in 32 − 15, they correctly regroup 32 as 2 tens and 12 ones, but then subtract to get 27 instead of 17 because they didn't cross out the 3 or count it as 2. Another frequent mistake is borrowing from the wrong place or borrowing when unnecessary—students sometimes borrow even when the ones digit is large enough. Watch for answers that are exactly 10 too high, which signals the forgotten reduction, or answers that don't make sense relative to the original problem.
