Subtract Whole Tens From 3 Digit Numbers Practice Activities
Printable Class 3 maths practice for subtracting whole tens from 3-digit numbers using place value, number lines, mental steps, and regrouping where needed.
Practice that builds confidence
What this skill builds
These Class 3 subtraction worksheets help children practise taking away whole tens, such as 20, 40, or 90, from 3-digit numbers. The focus is on place value: hundreds usually stay the same, tens reduce, and ones remain unchanged unless regrouping is needed.
The printable activities include clear sums, mixed practice, and problems that encourage children to think in tens rather than count back one by one. Learners meet examples like 468 − 30 and more careful cases such as 304 − 50, where regrouping from the hundreds place is needed.
Subtracting whole tens from 3-digit numbers strengthens a child’s understanding of place value and mental subtraction. Children learn that subtracting 30 means subtracting 3 tens, not 3 ones. In a sum like 576 − 40, the ones digit stays 6, the tens digit changes from 7 to 3, and the hundreds digit stays 5.
Progression in the worksheets
The practice can move from simpler questions where no regrouping is needed, such as 742 − 20, to questions where the tens place is not enough, such as 612 − 50. In these cases, children learn to exchange 1 hundred for 10 tens, turning 6 hundreds and 1 ten into 5 hundreds and 11 tens before subtracting 5 tens. This makes the written method meaningful rather than mechanical.
Parent routine at home
Start with a quick oral warm-up: ask, “What is 390 minus 10? minus 20? minus 30?” Then let your child solve one row of worksheet sums and explain two answers aloud. Encourage sentences such as, “I subtracted 4 tens from 8 tens.” If an answer looks wrong, ask the child to check by adding the tens back: 436 − 20 = 416, and 416 + 20 = 436.
Classroom uses for teachers
Teachers can use these printables for maths practice, revision, small-group support, or independent work after teaching subtraction of multiples of 10. They also work well in centres with base-ten blocks, place value charts, or open number lines. For confident learners, ask them to sort questions into “no regrouping” and “regrouping needed” before solving.
Common errors to watch for
Some children subtract from the ones place by mistake, changing 583 − 40 into 543 or 579 without a clear reason. Others reduce the hundreds digit unnecessarily. In regrouping questions, they may forget that 1 hundred becomes 10 tens. A simple check is to ask whether the answer should be close to the starting number and whether only tens are being removed.

Why iBloom worksheets help
The iBloom activities give repeated, focused practice on one exact idea: subtracting whole tens from 3-digit numbers. The layout keeps attention on hundreds, tens, and ones, while the mix of examples helps children build fluency, spot patterns, and become more confident with both mental and written subtraction.
Helpful answers
Frequently asked questions
What does subtracting whole tens from a 3-digit number mean?
It means taking away a multiple of 10, such as 10, 20, 30, or 90, from a 3-digit number. For example, in 684 − 50, the child subtracts 5 tens from 68 tens, giving 634.
Do these worksheets include regrouping?
Yes, practice can include both types: questions where the tens digit is enough, such as 756 − 30, and questions where regrouping from the hundreds place is needed, such as 402 − 60.
How can I help my child solve these without counting back by ones?
Ask your child to think in tens. For 527 − 40, say, “Take away 4 tens from 52 tens.” Number lines, place value charts, and base-ten blocks can also help children see the change.
What is a good way to check the answer?
Use addition to reverse the subtraction. If 638 − 70 = 568, then 568 + 70 should return to 638. This helps children catch place value mistakes.
Which mistakes are common in this topic?
Children may subtract from the ones digit, change the hundreds digit when it is not needed, or forget to regroup 1 hundred as 10 tens. Encourage them to name the tens being subtracted before writing the answer.
