Checking Subtraction with Addition Worksheet Download
This math worksheet practices checking subtraction with addition. Each problem shows a three-digit subtraction with an answer already written, such as 604 − 238 = 476. Students add the answer to the number that was subtracted, 476 + 238 = 714, and compare it with the starting number: 714 is not 604, so the answer is wrong. About half the answers are right, and the wrong ones are the real mistakes students make, like forgetting to regroup.
