Subtract Whole Tens From 3 Digit Numbers Practice Activities
Class 2 maths worksheets for practising subtraction of whole tens from 3-digit numbers using place value, number lines, and mental strategies.
Practice that builds confidence
What this skill builds
These Class 2 subtraction worksheets help children practise subtracting whole tens, such as 240 - 30 or 586 - 70, from 3-digit numbers. The focus is on understanding that only the tens place changes unless regrouping across a hundred is needed.
The printable activities include varied sums, place value thinking, number line support, and mixed practice so children can move from guided subtraction to confident mental maths. They are useful for revision, homework, maths centres, or extra practice after learning 3-digit numbers.
Subtracting whole tens from 3-digit numbers strengthens a child’s understanding of hundreds, tens, and ones. In examples like 368 - 40, children learn that 40 means 4 tens, so they subtract from the tens part while keeping the ones unchanged. This helps them see subtraction as changing the value of a number, not just crossing out digits.
Progression in the worksheets
The practice can begin with examples where no regrouping is needed, such as 452 - 20 or 731 - 50. Children then meet sums where subtracting tens crosses into the previous hundred, such as 304 - 60 or 520 - 80. These questions encourage careful place value reasoning: 304 - 60 can be thought of as 304 - 4 tens - 2 tens, or counted back by tens.
A simple home routine
Parents can use one row of sums at a time and ask the child to say the number aloud before solving. Try this routine: underline the tens being subtracted, ask “How many tens are going away?”, solve mentally, and then check by adding the tens back. For 675 - 30 = 645, the check is 645 + 30 = 675. This makes practice calm and purposeful.
Classroom uses for teachers
Teachers can use these printables for warm-ups, independent practice, remedial support, or small-group maths centres. A teacher may first model a few questions with base-ten blocks or a place value chart, then let children complete similar problems on paper. The worksheets also work well for quick observation: children who change the ones digit, skip a hundred incorrectly, or count back by ones may need more concrete support.
Common errors to watch for
Some children subtract the digit 3 from every place in 586 - 30 and write 253 or 556. Others forget that 10 tens make 100, so they struggle with numbers like 402 - 50. Encourage children to look at the whole ten as a group of tens, not as a single digit. Ask them to estimate first: the answer to 402 - 50 should be a little less than 400, not more than 400.

Why iBloom worksheets help
These iBloom worksheets give steady, focused practice without mixing in unrelated subtraction skills too early. Children meet the same idea in different layouts, which supports fluency and reduces guesswork. A child-friendly strategy is: “Keep the ones, subtract the tens, and check the hundred if you cross it.”
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 20, 40, or 70, from a number with hundreds, tens, and ones, such as 356 or 704.
Should my child use borrowing for every question?
No. Many questions only need the tens digit to change, such as 486 - 30 = 456. Borrowing or regrouping is needed only when there are not enough tens in the number.
How can I explain 304 - 60 to a Class 2 child?
Use place value language: 60 is 6 tens. Since 304 has no tens, show that one hundred can be changed into 10 tens. Then subtract 6 tens to get 244.
Are these worksheets suitable for mental maths practice?
Yes. The sums are focused on subtracting multiples of 10, so children can practise counting back by tens and using place value instead of lengthy written methods.
What is a good way to check the answer?
Ask the child to add the whole tens back. For example, if 638 - 50 = 588, then 588 + 50 should return to 638.
