About this worksheet
Subtracting within one thousand asks a third grader to take away ones, tens and hundreds, regrouping when the top digit in a place is smaller than the digit below it. For example, to take 8 ones from 3 ones, one ten is regrouped as ten ones. On this worksheet your child sees twelve plain subtraction problems and writes the difference.
Building Confidence needs regrouping in one place only, On Level regroups in the ones or the tens, and Challenge Me regroups across a zero, as in 703 - 258, where the tens place has nothing to give. There are no word problems here; those have their own worksheet. Ask your child to check each answer by adding it back.
What your child will learn
- Subtract ones, tens and hundreds in order
- Regroup a ten or a hundred when a digit is too small
- Regroup across a zero
Common Core standard: 3.NBT.A.2
Worked example
703 - 258: there are no tens to give, so regroup 1 hundred as 10 tens, then 1 ten as 10 ones. 13 - 8 = 5, 9 - 5 = 4, 6 - 2 = 4. The difference is 445.
Common mistake
Subtracting the smaller digit from the larger in every column, so 703 - 258 comes out as 555.
Helpful hint
Check by adding: the difference plus the number you took away should make the start.
