Two-Digit Subtraction with Renaming
Learning Objective
I can subtract two-digit numbers with renaming (borrowing).
Key Concepts
When subtracting 25 from 83, you can't subtract 5 ones from 3 ones, so you need to regroup.
Regrouping means taking 10 from the tens place and adding it to the ones place to make a larger number to subtract from.
After regrouping, 83 becomes 7 tens and 13 ones, allowing you to subtract 25 and get the answer 58.
Practice Questions
This lesson includes 3 practice questions to reinforce learning.
View questions preview
1. Solve 62 - 38 using the regrouping method. Show your work by writing out the new tens and ones values after regrouping.
2. Write down a subtraction problem (using two 2-digit numbers) that requires regrouping to solve. Explain why regrouping is necessary in the problem you created.
3. Explain in your own words why we sometimes need to 'borrow' or regroup when subtracting two-digit numbers.
