Subtract 2 Digit Whole Tens From 3 Digit Numbers Practice Activities
Class 4 children practise subtracting whole tens such as 20, 50, or 90 from 3-digit numbers using place value and regrouping when needed.
Practice that builds confidence
Place Value Behind the Skill
These Class 4 mathematics worksheets focus on subtracting 2-digit whole tens from 3-digit numbers. Children practise examples such as 346 - 20, 502 - 70, and 680 - 90 while keeping attention on tens and hundreds place value.
The printable activities include vertical subtraction, horizontal equations, and short word problems. Some questions can be solved mentally, while others require careful regrouping across tens and hundreds.
A 2-digit whole ten has zero ones, such as 30, 60, or 90. When subtracting it from a 3-digit number, the ones digit usually stays the same. The main work happens in the tens place, and sometimes the hundreds place is used for regrouping. For example, 458 - 30 changes 5 tens to 2 tens, giving 428.
When Regrouping Is Needed
If the tens digit is smaller than the tens being subtracted, children must regroup one hundred as 10 tens. In 412 - 70, 1 ten is not enough to subtract 7 tens. Regroup 4 hundreds as 3 hundreds and 11 tens, then subtract 7 tens to get 342. This reinforces why digits cannot be changed separately without thinking about place value.
Parent Practice Routine
At home, say a 3-digit number and ask your child to subtract a whole ten mentally, then explain which digit changed. Try 276 - 40, 631 - 20, and 704 - 80. For regrouping questions, let the child draw hundreds, tens, and ones or write the expanded form before using the standard method.
Classroom Uses
Teachers can use these worksheets after lessons on 3-digit subtraction, as maths centre practice, or for quick checks on regrouping with tens. They also work well for comparing mental strategies: counting back by tens, using a number line, expanding the number, or applying column subtraction.
Common Errors to Watch
Children may subtract from the ones digit because the subtrahend has two digits, or they may reduce the hundreds digit without adding 10 tens. Some write 412 - 70 as 442 by adding instead of subtracting after regrouping. Ask them to estimate first so they know the answer should be less than the starting number.

Why iBloom Worksheets Help
iBloom worksheets isolate this exact subtraction step so Class 4 children can master it before moving to larger mixed problems. The practice balances mental calculation with written methods and includes enough regrouping to build accuracy. A child-friendly strategy is: check the ones, subtract the tens, regroup from hundreds only if the tens are not enough, then estimate to check.
Helpful answers
Frequently asked questions
What are 2-digit whole tens?
They are 2-digit numbers with zero ones, such as 10, 20, 30, 40, 50, 60, 70, 80, and 90.
Does the ones digit change in these subtraction problems?
Usually it does not, because a whole ten has zero ones. The tens digit changes, and the hundreds digit may change when regrouping is needed.
When should a child regroup from the hundreds place?
Regroup when the tens digit in the 3-digit number is smaller than the tens being subtracted, such as 304 - 60.
Can these problems be solved mentally?
Many can be solved mentally by counting back in tens, but regrouping examples should also be practised with written place value steps.
How can I check whether my child's answer is reasonable?
Ask whether the answer is less than the starting number and whether the ones digit stayed the same unless the problem involved a larger subtraction context.
