Subtract Whole Tens From 3 Digits Practice Activities
Grade 3 worksheets for subtracting multiples of ten from 3-digit numbers using place value, mental math, and careful regrouping when needed.
Practice that builds confidence
What students are learning
These Grade 3 math worksheets help children practise subtracting whole tens, such as 20, 40, or 70, from 3-digit numbers. Students focus on how the tens place changes while the ones place often stays the same.
The printable activities include straightforward equations, mixed practice, and problems that encourage place-value thinking. Children meet examples with and without crossing a hundred, building confidence before moving into more complex subtraction.
Subtracting whole tens from 3-digit numbers is a place-value skill. Children learn that in 472 - 30, the 3 tens are subtracted from the 7 tens, giving 442. They also see that the hundreds and ones digits may stay the same when no regrouping is needed. Useful vocabulary includes hundreds, tens, ones, multiple of ten, subtract, and difference.
How the practice progresses
The worksheets begin with clear problems where the tens digit is large enough to subtract from directly. Practice then moves toward examples such as 506 - 40 or 304 - 50, where children must think across a hundred. This progression helps students connect written subtraction to mental math, base-ten blocks, number lines, or expanded form such as 300 + 40 + 8.
Parent routine for home practice
Choose a few problems and ask your child to say what is being subtracted: 60 means six tens. Have them point to the tens digit in the 3-digit number, solve, and then check by adding the tens back. For example, after 638 - 50 = 588, check 588 + 50 = 638. If a problem crosses a hundred, draw quick tens sticks or count back by tens: 402, 392, 382, 372.
Classroom uses for teachers
Teachers can use these printables for subtraction warm-ups, small-group reteaching, math centers, or independent practice after a place-value lesson. They also work well as a quick check to see which students are subtracting by place value and which are trying to count back one by one.
Common errors to watch for
Some students subtract from the ones digit because they see the zero in 30 and think nothing changes. Others change the hundreds digit too early or forget that crossing a hundred may require regrouping. A child-friendly strategy is: Name the tens, look at the tens place, subtract tens, then check with addition.

Why iBloom worksheets help
iBloom worksheets keep the focus narrow: subtract whole tens from 3-digit numbers. That lets children practise enough similar examples to notice patterns, while mixed numbers and occasional regrouping prevent guessing. The clean layout supports careful writing, place-value reasoning, and steady Grade 3 subtraction fluency.
Helpful answers
Frequently asked questions
What does subtracting whole tens from 3-digit numbers mean?
It means subtracting a multiple of ten, such as 20, 50, or 90, from a number with three digits. Children use place value to subtract tens rather than subtracting ones.
Do these worksheets include problems that cross a hundred?
Yes. The practice can include examples where students subtract tens and move into the previous hundred, such as 304 - 50. These problems help children understand regrouping through place value.
What should my child do if the tens digit is too small?
Encourage your child to think of the number in hundreds, tens, and ones. They can trade one hundred for ten tens, draw a quick model, or count back by tens to find the difference.
How can students check their answers?
They can add the subtracted tens back to the answer. For example, if 725 - 60 = 665, then 665 + 60 should return to 725.
Why is this skill important in Grade 3 subtraction?
It strengthens place-value understanding and mental subtraction. Students who can subtract whole tens confidently are better prepared for 3-digit subtraction with regrouping and word problems.
Is this subtract whole tens from 3 digits worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
