STEP-BY-STEP SOLVED EXAMPLES
Problem 1: 30 - 3
To solve 30 minus 3, we start in the ones column. Since we cannot take 3 from 0, we must regroup. We take 1 ten from the tens place (leaving 2 tens) and add it to the ones place, making it 10 ones. Now, 10 - 3 = 7. Finally, bring down the remaining 2 tens. The result is 27.
Problem 4: 45 - 32
This problem does not require regrouping. First, look at the ones column: 5 minus 2 equals 3. Next, look at the tens column: 4 minus 3 equals 1. Combine the results for an answer of 13.
Problem 13: 28 - 6
Start with the ones place: 8 minus 6 equals 2. Since there is no number in the tens place for the second value, simply bring down the 2 from the first number's tens place. The final answer is 22.
TEACHER & PARENT TIPS
When introducing two-digit subtraction, encourage students to use physical manipulatives like base-ten blocks to visualize the process of regrouping. Have them highlight the ones column first to remind them where to begin. For students who struggle with alignment, using graph paper can help keep their columns straight. Finally, try breaking the worksheet into smaller sections of five to ten problems to prevent fatigue and keep learning sessions positive and engaging for young minds.
