Grade 3 Subtraction — Durable Learning Test
Problem: 900 − 347
A farmer had 900 eggs. He sold 347. How many eggs remain?
Subtract the number sold from the total.
Before choosing an answer, explain how you would solve the subtraction. Type your answer.
Choose your answer:
Hint:
You must regroup because 0 − 7 cannot be done without borrowing. Apply regrouping and borrowing method. See explanation on how to do it.
Explanation:
8
9
10
900
− 347
---------
553
Regroup hundreds, tens, and ones:
Borrow 1 ten → ones become 10 + 0 = 10
Borrow 1 hundred → tens become 10 + 0 - 1 = 9 because you give 1 ten to ones
Hundreds becomes 9 - 1 = 8 because you give 1 hundred to tens.
If student chose 553: Correct — regrouping was done properly in ones and tens.
If student chose 543: Tens place error — re-check 9 − 4.
If student chose 563: Hundreds place error — re-check 8 − 3.
If student chose 533: Ones place error — re-check 10 − 7.
Reflection:
Did regrouping help you subtract accurately?
