Max Rescues Lost Horses: Subtraction Sprint

About this Grade 2 Subtraction With Borrowing Drill

Subtraction-with-borrowing (also called regrouping) is a pivotal skill that bridges the concrete thinking of early Grade 2 to more abstract math reasoning. At ages 7-8, students are developmentally ready to understand that ten ones can become one ten, and vice versa—a concept that unlocks their ability to solve real-world problems like figuring out change at a store or calculating how many cookies remain after sharing. Without mastering this skill now, students will struggle with multi-digit subtraction in Grade 3 and beyond. This worksheet helps students practice the specific steps: identifying when the ones place is too small, borrowing ten from the tens place, and completing the subtraction correctly. Regular drill practice builds automaticity and confidence, making the mental process faster and more reliable.

What your student will practice

• Identify when borrowing is necessary in two-digit subtraction problems
• Correctly regroup tens into ones to solve subtraction problems
• Execute multi-step subtraction-with-borrowing with accuracy and consistency
• Apply borrowing strategy to word problems involving subtraction

Common mistakes to watch for

Many Grade 2 students forget to reduce the tens digit after borrowing, writing answers like 23 when solving 32 − 15 (they subtract 5 from 2 in the ones place by borrowing, but then ignore that they borrowed). Others miscount how much they borrowed, thinking they added 5 instead of 10 to the ones place. A third common error is borrowing even when unnecessary—for example, borrowing in 34 − 12 because they haven't yet learned to recognize that 4 ones minus 2 ones works without regrouping. Watch for crossed-out numbers that don't match the actual regrouping, and check whether the student can explain their steps aloud.
