About this worksheet
Two-digit subtraction asks students to manage place value while taking one amount from another. It is easy for a child to subtract the smaller digit from the larger digit in each column, even when that is not what the problem says. Regrouping adds another layer because one ten must be traded for ten ones before the ones can be subtracted. This worksheet keeps the focus on two-digit minuends and subtrahends while varying the question type. Students solve equations, compare quantities, find missing parts, and decide whether regrouping is needed. Encourage your child to read the whole number, not just each digit, before beginning the calculation. If the answer seems larger than the starting number, pause and recheck the places carefully.
What your child will learn
Subtract one two-digit number from another
Recognize when regrouping is needed
Use missing-part models for subtraction
Solve comparison subtraction problems
Worked example
For 83 - 47, trade one ten so 83 becomes 7 tens and 13 ones. Then 13 - 7 = 6 and 7 tens - 4 tens = 3 tens, so the answer is 36.
Common mistake
Subtracting the smaller digit from the larger digit in each column instead of regrouping.
Helpful hint
The top number is the whole. Regroup only when the top ones are smaller.
